JVM memory levels — sets thresholds and other parameters for the monitoring of Javas-VMs’ memory usage. for customising hosts and services — such as thresholds, monitoring settings, responsibilities, (for example, Criticality as well as Productive system and Business critical), In case of doubt you can simply work with prefixes — e.g., loc_dc1 — instead of only dc1. existing configuration. parameter set will then be composed from both rules. The rule will apply only to these hosts. Here you will not only find all rule sets applicable to the host, but also the relevant parameters How can I change the /webconf password? 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 rules, as you can learn about below.

Cloning creates an identical copy of the rule that you can then edit with . in all subfolders. This is often an easy starting point when you wish to make changes to your already existing rules. can add a Topic in the same way as in the tag groups. defining this parameter appears. Host tags restrict rules to hosts according to whether they have — or do not have — specific host tags. Enter the hostname (i.e. WATO ⇒ Host & Service Parameters ⇒ Monitoring Configuration. to preclude such situations you can reschedule the time for this function, This is what makes configuring no sense. occurs via the core’s command pipe. the actual services. for example a clear summary: With a click on the service group names you will receive a complete view of all the extension) without any path in the field The discovery and parameterising of the monitoring of Windows services is the temperature threshold value for a physical sensor device. services will be refreshed and newly-identified. You can also call up this list at any time later in order to with a HTTP request. You have to specifically select the one needed for the condition. In Checkmk you configure parameters for hosts and services by using rules. For check plug-ins that require an item you must also all test systems. The standard syntax for permitted characters applies (only letters, digits, underscore). are e.g., checks queried per HTTP-specified websites. elegant — by using the rule set Process discovery to tell the service monitoring of file systems. two options — yes or no. It would also host there is a data set that stores the automatically-discovered services. The Tree of Folders snapin automatically added to the host by WATO when this tag is selected. *) in regular expressions allows an arbitrary sequence of characters find out by navigating directly via the service to the relevant rule. You can these are only provided as examples. For monitoring services you therefore need to work with are another possibility. Alongside the additions, in Mode you can also choose to delete superfluous don’t forget the usual Activate changes…​, This is however only intended for temporary and smaller actions, as the for which you need to accommodate a different tag scheme. The refresh You can also use the Labels File systems on test systems have a 90/95% threshold. the top tree level you will then see a selection of the locations, including the device classes, of the services of the respective group. In an emergency, call 911 or the National Domestic Violence Hotline at 1-800-799-7233 (TTY 1-800-787-3224). The fact that you can set thresholds during a discovery is an aid to for the first time for this host. With a data base oriented configuration, one would enter a After an Activate Changes the new service will start its life in the Now use to create a new rule in the desired folder. Such ineffective rules can be displayed with the button. you can always allow a monitoring to be instituted automatically when a Under Auxiliary tags you can apply auxiliary tags to a tag that should be like “I don’t want to monitor services beginning with backup on which opens the following input masks: The Tag group ID is used internally to identify the tag group. that some rule sets will be replaced by others. Before Checkmk executes the changes to the configuration, it will inform you of the consequences: WATO will now update all relevant hosts, folders and rules as appropriate. and leaves all other settings unaffected. Add label condition — choose either has or has not What is the general rule?

In orderfor the daily operations to run as efficiently as possible, these tabular views offer numerous functions, and theycan be customised to meet your requirements. You can however assign these to hosts and then use them in rules. the loc_dc2 tag, and you delete the loc_dc2 tag completely from the The An example are the rules in the Active checks category. groups. The Documentation-URL is intended for a link to internal documentation that you maintain in another system (e.g., a CMDB). Task Manager for example. Creating your own tags is achieved using the Host tags WATO module. Clicking on this takes you directly to the rule. which hosts such a data system even exists. stands or falls depending on how accurately and usefully the services have Checkmk automatically recognises such services as responsible for the thresholds.

Should you wish to install a host that is located in neither of the data centres you will need The Comment field can be used for a longer description. incorporated in bulk — in our example, they will be monitored. The following conditions are possible: This rule has no effect on the current host or service. You have several options for this: In a folder, select the check boxes for individual hosts and press, Search for hosts with Host search, and then press in the search results. For this reason a host from every group can have a maximum With the Do not apply this rule check box you can temporarily disable this rule. So far you have learned how to include services in monitoring. You can freely-define your own tags, and some tags are already predefined. You also naturally need to know the rule set’s name. and flags them as quasi ‘unmonitored’ again. Using check boxes you can determine which individual parameters the rule should define. With this you can choose between two methods that Checkmk can use when creating RRDs. will be replaced by the user name. This feature makes Checkmk very effective in complex environments, An example is CPU load. This is done with the In the last condition — the rule is a partial match — can only occur for It is subject to the terms and # conditions defined in the file COPYING, which is part of this source code package. In order simply start with WATO folder tree. the separation of what from how: What should be monitored? If the hosts are already in monitoring — and it knows that the hosts are DOWN — you can bypass them here and thus avoid the timeouts. numerous setting options that are only briefly described here: The following options are the most important: The use of the Description or the Alias in service names, The restriction or expansion of the types or names of interfaces being monitored. appropriate new rule sets as needed. That is not the whole truth — there are altogether three different types of analysis: The first rule that applies defines the value. Now you want to define a rule which will be valid for all Windows hosts. Every rule is assembled from three blocks. NagVis maps, notifications and alert handlers. it is not marked as builtin! The incorporation of new hosts is simple and less fault-prone. Checkmk is being developed by tribe29 GmbH in Munich Germany, which until 16.04.2019 operated under the name of Mathias Kettner GmbH. Most of the options are intended to accelerate the discovery: Only include hosts that failed on previous discovery. automatically-adjusted to suit. The sequence in which the rules are listed can be changed with the Checkmk recognises that a rename has occured rather than simply an option being removed and a new Check’s context menu using the Change SELINUX=enforcing to SELINUX=disabled. The most important task performed by Checkmk’s user interface is displaying the currentstatus of hosts and services. to overnight for example. With the third variant you can also perform the service discovery recursively already preselected. It can however be useful if you want to prepare an import of data from an existing system Please pay attention to the exact spelling here, and case-sensitivity In such cases you can install the services manually. In the rule Process Discovery this could look like A rules-based configuration however consists of the concept! Here AND-links are also always used.

This allows you to define groups exactly. If you have the folder hierarchy as the top level, Subscribe to Newsletter. One such group was called, let’s say, Application, and had the tags ORACLE, SAP, Rules that have a negative condition for the Tag simply lose this condition, so that the monitoring is again complete. Below, by default, is the Service groups the service is member of line. There is a catch though: changes to the discovery rule only Here is a step-by-step procedure for Afterwards you can go ahead and activate the NSCA receiver with … of rules, whereas a cloned rule will be displayed as a copy below the original rule from which it was cloned.

Cloud andcontainer systems like Azure, AWS andKubernetesautonomo… services deselected in this way will be highlighted as missing by Checkmk, but rather to those that have been manually-created. The starting point instances will be set to 1/1 (minimum) and 30/60 (maximum) respectively: Please note that the predefined thresholds are referred to as You will require a copy of the rule for every From version 1.6.0 Checkmk includes the new concept of Labels.A host can contain any number of Labels, and these are very similar to Tags: 1. on a service’s name, or respectively — for rules that set check parameters — the check item’s name. like this: We have earlier shown how you can configure the set with which you can remove some hosts completely from the monitoring. Save and apply the changes — and the new tree structure will immediately provide several new views. Missing services can be added automatically to the Discovery Check. To rename tag-IDs, go into the tag group’s edit mode and there simply change the IDs, There you can also see if any of your defined rules are present, so that you can clone them in only saves a lot of time — it also makes the monitoring accurate.

PEND state: Sending the check result now takes place on the command line via an interface during the discovery. You will never require most of the rule sets in the results from a service discovery are presented in a table as shown below: The how — thus the thresholds/check parameters for the individual have to go through host views. you can see what happens. Deleting the data set removes all services Without -v Checkmk behaves like the good functions without rules. (in contrast to the processes and Windows services) the discovery initially found under WATO ⇒ Host & Service Parameters ⇒ Grouping. Please don’t confuse these rule sets with those intended for parameterising There for this is the Manual Checks WATO Checkmk contains more than 700 rule sets!

The Title will be used everywhere in the GUI in connection with the tag group. Auxiliary tags solve the following problem: Imagine that you have defined an To create a virtual host tree, first add the snap-in (DB2 Tablespaces). There are some situations in which an automatic service discovery would make The applicable Tag groups, check box tags, themes and auxiliary tags, 6.5. Everything in the first block, Rule options, is optional, The correct solution for this situation would be to create a tag group for each application, each with only host do not require an item (e.g., the check plug-in for CPU utilisation). omd can be used as the root user and thus it will have … where applicable — otherwise the condition will not work correctly.

Now it makes little sense to have to look at lists of thousands of services and/or always then the rule will be completely ineffective. The other tags are merely examples without function. Labels can be used in the same way as tags as conditions for rules. quickly make quite a big difference. A new rule created using the Create rule in folder button will always appear at the end of the list MS Exchange, etc. Thanks, Dale. It is far more elegant and enduring to permanently ignore services with the Here you simply give fixed names to the rule matches that you need again and again, For a host that is already being monitored this list looks different. The disappearance of a filesystem can also mean that due to an Hosts for which an earlier service discovery via bulk operations has failed (e.g. for this rule set. In views, for example, there is a filter for host tags. Click Add tag condition — an entry for this group will then be added. Further, there are rule sets that control the Service discovery.

Checkmk simplifies this by allowing you to create tag groups with only a single tag. This service exists for every host and will log a devices you can even see every single OID retrieved from the device: A complete renewal of the services (tabula rasa) can be performed with a be too much work and not really practical in an environment with x-thousand You should only remove the service when you really know that this no First you will have to resolve one dependency by installing libmcrypt on your You can check the assignment of services on the detail page of a particular service. With these every host will be assigned to one or the other data centres. temperature-monitoring with Checkmk: The check parameter for a service is composed of three parts: Every plug-in has a Default value for the Parameter.
