Check_MK will store all of its files in the /opt/omd directory. The tags for this group are referenced internally by Checkmk. That means that all hosts without an explicit setting for this tag group will be in and which are not. This is not applicable to services that are created by a service discovery, but rather to those that have been manually-created. The analysis mode with ‘traffic lights’, 6.1. You Hi, I'm using passive and active checks on Icinga 1.6.1, but now most of passive checks aren't processed by icinga or are processed very late.Also simple checks like check_ping take much too long. The second block is different for every rule. The numbers show the number of rules already You will require a copy of the rule for every Since Checkmk’s Version 1.2.8, without exception these are configured with a single rule set. Constructing a tree-view from host tags. The Tree of Folders snapin set with which you can remove some hosts completely from the monitoring. host tags you can also incorporate the folder structure in such trees in which Inventory and manual checks can be used in parallel. existing configuration. A number of the previous rule sets have been rendered ineffective through this action. And on the command line, with many commands you can select all hosts having the foo tagline It only appears in a rule’s edit mode. If however a positive condition with the tag exists, you will receive the above warning Selecting the check box sets a tag, otherwise the tag will not apply. You can also define that a tag is not checkmk - Awk script for generating C unit tests for use with the Check unit testing framework. If an accesspoint is not longer reachable, the checks also triggers a critical state. rules or whether you wish to delete the rules completely. Checkmk is fundamentally case-sensitive! This determines whether SNMP data is evaluated. If we assume that mysrv123 is a test system, and that in each case the first relevant You have to specifically select the one needed for the condition. Secondly, a ‘traffic light’ symbol appears in every line, the colour of which shows whether and/or Checkmk’s official documentation doesnt have anything related to passive checks. With a larger number of hosts we propose using {inventory_services_rules}. Automated and manual web checks. This is, so to The Linux agent sends the status of all NFS mounts, if the command line utility waitmax is available (it is is used to avoid hanging if the NFS server is not responding). Alternative display name for services — defines alternative names for services’ displays. But because another rule higher in the hierarchy has priority this rule is ineffective. a third option for selection — for example, Not in a datacenter. Such tag groups are also two options — yes or no. This feature makes Checkmk very effective in complex environments, You can display this as a tree view via the These are managed with the Predefined Conditions WATO module. For this reason, with Checkmk you will find an abundance of rules If an entry matches one service is created according to the entry (if it's not already existing). Here as an example is a search for host check. the Checkmk instance was installed, and they are a part of the WATO sample The inventory function of this check helps you to auto-detect the services that should be monitored on your hosts. A host that possesses either of these tags will always automatically Hi Can some one please point to any documentation to create and run a passive check. Reads apache, nginx configs and use info for checks. Add label condition — choose either has or has not You can access this parameter page with the symbol in a host’s Firstly, a second button for setting rules The incorporation of new hosts is simple and less fault-prone. The so-called auxiliary tags The name of the service as string. It is essential that Those are just being displayed as a further information. It is getting UNKNOWN if the service is missing on the system at all. module, rather it is located in the Manual checks module. You can leave Topic blank. defining this parameter appears. using in the bottom left of the sidebar. Some users have attempted to display the application running on a host in a tag group. The standard syntax for permitted characters applies (only letters, digits, underscore). Host tags are organised in groups. You can also create your own topics and use these to arrange your tags clearly in a summary. You can also use the Labels So your filesystem might be at 100% in a situation where root still has 5% free space available. This check is also cluster-aware. A rules-based configuration however consists of the concept! calls the hosts, filtered per branch. This rule accesses and defines parameters. quickly make quite a big difference. variable. All rights reserved. applied to the start of the name. Reads apache, nginx configs and use info for checks. It can however be useful if you want to prepare an import of data from an existing system Check MK (raw) ist running and the agent on then Windowsserver is running. With the Do not apply this rule check box you can temporarily disable this rule. also manage the hosts. Reads apache, nginx configs and use info for checks. Checks the current state of a Windows service. simply start with WATO folder tree. Nevertheless, every IT environment is unique, so that often very specialised requirements can arise. ), but also check for changes. You can change this behaviour to regular expressions by prefixing host names with a tilde (~). Every individual parameter will be set by the first rule that defines this parameter (check box selected). Tools like copy & paste, and bulk operations can simplify the work, but the basic problem remains — how can you identify and implement a concept? Each level of the hierarchy takes you straight to a following the point. How to do this is explained in the article on the hosts. Basic information on the installation of Checkmk, Basic Principles of monitoring with Checkmk, Monitoring network services (Active checks), User Management with LDAP/Active Directory, System Monitoring with Checkmk – Part 1: The Basics, System Monitoring with Checkmk - Part 2: Advance Topics. Simply install mk_inventory.linux on your Linux server(s) and enable the inventory check with a new rule set in WAT… One thing we have so far not mentioned: In the above example there is a rule for These will not be shown as a selection field in the host mask, rather they will be displayed as a check box. Checkmk recognises that a rename has occured rather than simply an option being removed and a new Every rule set is responsible either for hosts or for services — never for both. rule sets in which a rule can define multiple parameters by selecting individual check boxes. shown and where you have the possibility of directly accessing the applicable rule sets. speak, an exception to the Checkmk principle that IDs once set are unchangeable. change using the handles. The following example shows a condition which all hosts will match whose names Here AND-links are also always used. This is the normal situation with rules that set simple parameters. host in WATO, or via the symbol in a folder’s list of hosts. In addition to the called Checkboxtags. But before we show you how you can define your own host tags with WATO, we should now explain a few terms. An example is CPU load. Modifying an existing tag group configuration appears to be a simple operation at first — but that is unfortunately not always the case, as it can have big impacts on an If you are not yet very experienced with the rule sets’ names, then the procedure via the But what values … The documentation provided here is meant as a quick introduction to the Checkmk Enterprise Editi (CEE). With these every host will be assigned to one or the other data centres. Mit der Checkmk-Dokumentation setzen Sie im Handumdrehen ein umfassendes Monitoring auf. Your tag group will then be displayed with the predefined What is the general rule? Creating your own tags is achieved using the Host tags WATO module. The assignment and the usage of these auxiliary tags is then done directly Save and apply the changes — and the new tree structure will immediately provide several new views. Treat this tag group only as an example. Each service is either {running} or {stopped} or in a transitional state like {starting} or {stopping}. Because some users really use many host tags, we have designed this For the Do not monitor this host tag a predefined rule is provided which will disable the host monitoring. By the way — the symbol for the parameter page is also found in the status window in every service’s context menu: A part of the rule sets is not included in the Host & service parameters the appropriate Tag ID is explicit — not only within the group but The topics have ‘only’ an aid for visualisation function, and have no influence on the actual configuration. Deleting and modifying existing tags and tag groups, 6.6. how this rule affects the current host, or respectively, service. As we have seen, the host tags are an important basis for defining rules. The Comment field can be used for a longer description. In a rule’s characteristics you can change its folder and thus ‘relocate’ it. I found some SQL things in [Manual Checks]. The conditions are therefore logically AND-linked: Here you have the option of using normal conditions as well as builtin. One Ubuntu 18.04 server with a regular, non-root user with sudo privileges. Checkmk already monitors many types of relevant data using a large number of its own standard check plug-ins. transfer). More on this later. The majority of the information here should apply to How to create your own tags, and what the predefined tags are about will be explained For check parameter rules a match with the item applies (e.g. The system’s service level. The group has the status builtin and can not be modified. Checkmk is available as Raw Edition, which is 100% pure open source, and as Enterprise Edition with a lot of additional features. You can create an exceptional rule very easily and directly in this way. It works like this: In the selection box choose a tags group. …​ displayed in the rule conditions as a list which can be expanded and collapsed using a small triangle icon. An example are the rules in the Active checks category. If you are unsure about the correct spelling of the name then please look at the output of the agent (cmk -d HOSTNAME). service is simpler. It can sometimes occur that there are rules that don’t apply to any hosts or services — either because you have made an error, or because the associated hosts and services have disappeared. The rules are stored in the same folders from which you Manual checks A part of the rule sets is not included in the Host & service parameters module, rather it is located in the Manual checks module. Please pay attention to the exact spelling here, and case-sensitivity The Documentation-URL is intended for a link to internal documentation that you maintain in another system (e.g., a CMDB). present in the relevant rule sets: Another method is via the button in the details for an existing A point-asterisk (. Unlike those in tag groups, you can in fact change the IDs of tags retrospectively. Windows 2012 tags. Deleting tags is achieved by editing the group, removing the tag and then saving the data. How to do this will be explained later. Monitoring is a complex matter. The following image shows the Filesystems (used space and growth) rule set with four host — so no item is required. During installation, Checkmk furnishes you with numerous tag groups: Defines what type of data the host receives from its agents. and create a new tree with Create new virtual host tree configuration. As usual but leaving the title unaltered in doing so. Defines whether the host should be monitored per IPv4 or IPv6, or both. Everything in the first block, Rule options, is optional, SSL, return status, DNS match. With these you can, e.g., set up an HTTP check for specific hosts. operating system tag group with the tags Linux, AIX, One such group was called, let’s say, Application, and had the tags ORACLE, SAP, The Title will be used everywhere in the GUI in connection with the tag group. the label in the usual form key`:`value. So that this doesn’t get confusing if you have many tag groups (e.g., because you have numerous The dollar sign at the end of transfer$ represents the end and thereby (e.g. Once the monitoring information is received, it executes the Checkmk checks and updates all passive services that are configured for the host. All other changes can impact existing hosts or rules that use the affected tags. Every rule is assembled from three blocks. different views. Every other host tag condition in a rule reduces the number of These are also host rules. MS Exchange, etc. for customising hosts and services — such as thresholds, monitoring settings, responsibilities, In this case, as always in WATO: The match is applied to the beginning of the host name. (DB2 Tablespaces). I only see 2 other Gude Checks. in some locations. Please do not mix up the service names with the display names of the services. Join thousands of sysadmins and receive free professional tips and tricks to help you monitor your IT-infrastructure. In summary, then: less work — more quality! The other tags are merely examples without function. What exactly that means depends on the type of operation. Check_MK will find all relevant checks automatically. If a parameter can be defined for hosts as well as services, there is a pair of applicable Please note, that the agent replaces spaces in the service names with underscores. you cannot do this with a single rule. Ergänzend zu @kdeutsch s Erklärung möchte ich vielleicht noch folgendes hinzufügen: Mit den Manual Checks bestimmts Du, welche Checks für einen Host durchgeführt werden, während bei den automatisch erkannten (und per Rule gesteuerten) der Checkmk-Agent das zurückliefert, was er eben auf dem Host so findet. In Checkmk you configure parameters for hosts and services by using rules. Automated and manual web checks. But I cannot find this check at WATO -> Manual Checks? other locations. If uncertain, you should go through the rule set (linked via the warning) and manually Then with Add new element Please be aware that there can nonetheless be situations in which manual corrections need to be made are another possibility. Click Add tag condition — an entry for this group will then be added. An example is Network interfaces and switch ports. Please note, that the agent replaces spaces in the service names with underscores. currently in effect for this host. Host tags restrict rules to hosts according to whether they have — or do not have — specific host tags. As part of this, I have a collection of old Nagios checks that I want to be able to use verbatim in CheckMK as legacy checks. automatically-adjusted to suit. This type of condition is intended for exception rules. It is also a good idea at the beginning to give enough thought to the The As a minimum I typically implement an SSH check as well as HTTP checks on any open web tag scheme so that possible later renames can be minimised. In case you are uncertain which rule set is responsible for which services, then you can best Via the Negate option you can define a reversed-exception. I want to monitor some MS SQL Server (2012/2017). Theoretically, every parameter for another rule can also be set individually here. This rule is applicable. Checkmk contains more than 700 rule sets! Item The name of the service as string. Checkmk Raw Edition — a free and 100% open-source version Checkmk Enterprise Free Edition — free, limited to two sites with 10 hosts each Checkmk Enterprise Standard Edition — requires a subscription Checkmk Enterprise then the rule will be completely ineffective. The symbol takes you directly to the rule set that defines File systems on test systems have a 90/95% threshold. forces an exact match. cannot be automatically updated. …​ This WILL work until the day a host has two applications — and that Fortgeschrittene Benutzer können damit das Beste aus ihrem Monitoring herausholen. both the number of virtual trees and their respective branches the loc_dc2 tag, and you delete the loc_dc2 tag completely from the Hier mal mein Eintrag in der Rules.mk: static_checks.setdefault('fileinfo', []) If you wish to create a new rule that defines a parameter for one or more hosts, there are several ", "How many CPUs and cores?
