Checkmk Werk 13693: Dedicated agent updater systemd units

by Moritz Kiemer

ID: 13693 Title: Dedicated agent updater systemd units Component: agents Level: 1 Class: Bug fix Version: 2.2.0i1 In case the linux agent is managed by systemd, the agent updater now comes with dedicated systemd units to trigger the update. This was required by the new agent conroller architecture, but it also has the advantage that the agent update is triggered indenpendently from the monitoring data transport. A misconfigured agent transport no longer locks you out of the host.

Checkmk Werk 13577: Service creation when pinging all IPv4/v6

by Timotheus Bachinger

ID: 13577 Title: Service creation when pinging all IPv4/v6 Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 When using the rule "Check hosts with PING (ICMP Echo Request)" in combination with "Ping all IPv4/6 addresses", only a service for the first matching rule was created. As a result, only one protocol on a dual-stack host was monitored. This is fixed now.

Checkmk Werk 13562: win_dhcp_pools: Free or used leases statistics are average values not absolute

by Lisa Pichler

ID: 13562 Title: win_dhcp_pools: Free or used leases statistics are average values not absolute Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 Via the command {{netsh dhcp server show mibinfo}} in the agent plugin {{win_dhcp_pools.bat}} the collected statistics about free or used leases are average and not absolute values. These average values refer to the last execution interval, see also the official docs in {{DHCP Service POG.docx}}: Task: Capture DHCP services scope usage statistics Purpose The following activity captures empirical data on DHCP service utilization. This data, which is collected daily (or multiple times a day) should be reviewed weekly. It will also be used to create monthly reports that are reviewed quarterly for SLA/OLA compliance. Service utilization statistics are different from system performance in that they measure the usage characteristics of the DHCP service, not the underlying infrastructure such as disk, memory, or processor. Procedure Option 2: Capture DHCP services scope usage statistics using Netsh command line utility This collection should be performed on a consistent schedule, during key times of the day, such as 08:00, 12:00, and 17:00. The information should be recorded in a log file with the date appended to the name, such as “DHCPScopeStats_200305.csv” (indicates a comma separated log for the month of May 2003). Enterprise environments with many DHCP servers can adopt this option into a parsing script feeding a SQL Server database. 1. Open a command shell by clicking the Start menu. Click Run, type cmd and click OK. 2. Type the netsh command: Netsh DHCP Server \\<servername> show mibinfo where you replace <servername> with the name of an authorized DHCP server. 3. Open the month’s csv log using WordPad and manually record the data as follows: “DATE TIME”,”DHCPServer Name”,”Scope IP”,”Total Addresses”,”IPs in Use”, “IPs Available” For example: 05/24/2003 16:58:00.000,sea_dhcpsvr01,192.168.12.0,200,140,60 05/24/2003 16:59:00.000,sea_dhcpsvr02,192.168.13.0,200,10,190

by Solomon Jacobs

ID: 13340 Title: view: sort perf-o-meter with missing value Component: Multisite Level: 1 Class: Bug fix Version: 2.2.0i1 When sorting the perf-o-meter missing values used to be treated as equal to all other values. This lead an incorrect sorting in a view. The missing entries are now treated as smaller than all other values.

Checkmk Werk 13636: Fix xinetd installation problem on SLES15

by Lars Michelsen

ID: 13636 Title: Fix xinetd installation problem on SLES15 Component: Other Components Level: 1 Class: Bug fix Version: 2.2.0i1 When trying to install Checkmk on SLES15 this failed, because the package dependency 'xinetd' could not be provided by the official package repositories. It is not possible to get xinetd from official SLES package repositories, because it has been dropped in favour of systemd. The switch to systemd is possible, if you can register regular services to the systemd unit system and let systemd manage your units. But in our case, where we have an xinetd process that is managed as part of an OMD site, this way will not work. Users were able to solve the situation locally by installing xinetd from 3rd party sources, like for example OpenSUSE.org repositories. However, this approach is not supported by SLES nor straight forward for users. To make the installation more straight forward again, we now drop the xinetd package dependency for all supported SLES distributions from our Checkmk packages and ship xinetd together with Checkmk.

Checkmk Werk 13576: Quoting of mk_redis commandline arguments

by Timotheus Bachinger

ID: 13576 Title: Quoting of mk_redis commandline arguments Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The section of the agent plugin mk_redis may contain the following error message: <<<redis_info:sep(58)>>> [[[127.0.0.1;6379|127.0.0.1|6379]]] Unrecognized option or bad number of args This was caused by invalid quoting of the command line arguments and is fixed now.

Checkmk Werk 13692: Checkmk agent: do not support systemd versions prior to 220

by Moritz Kiemer

ID: 13692 Title: Checkmk agent: do not support systemd versions prior to 220 Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The Checkmk agent no longer uses systemd versions prior to 220. These systemd versions either do not support features the agent may need (e.g. setting of the REMOTE_ADDR environment variable) or they are buggy (e.g. <a href="https://github.com/systemd/systemd/issues/1742">ExecStopPost</a>) On theses systems, the agent will try to use xinetd.
