Module: check_mk Branch: master Commit: 30bcc57fce9c6fec48ece4cc0fc8e5526c532f3e URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=30bcc57fce9c6f… Author: Andreas Boesl &lt;ab(a)mathias-kettner.de&gt; Date: Mon Jan 26 16:56:57 2015 +0100 #1675 esx_vsphere_hostsystem.cpu_util_cluster: Averaged CPU utilization of all cluster nodes This new check allows you to monitor the average CPU utilization over all cluster nodes. Each node has informations about the total available MHz and the actually used MHz for computing. The actual usage of a cluster is calculated by the formula <i>(total_used_mhz / total_avail_mhz) * 100</i> Via WATO you can configure a set of WARN and CRIT levels for specific node counts. --- .werks/1675 | 13 ++++ ChangeLog | 1 + checkman/esx_vsphere_hostsystem.cpu_util_cluster | 32 +++++++++ checkman/esx_vsphere_hostsystem.mem_usage_cluster | 5 -- checks/esx_vsphere_hostsystem | 76 +++++++++++++++++++++ web/plugins/wato/check_parameters.py | 29 ++++++++ 6 files changed, 151 insertions(+), 5 deletions(-) diff --git a/.werks/1675 b/.werks/1675 new file mode 100644 index 0000000..07c644a --- /dev/null +++ b/.werks/1675 @@ -0,0 +1,13 @@ +Title: esx_vsphere_hostsystem.cpu_util_cluster: Averaged CPU utilization of all cluster nodes +Level: 1 +Component: checks +Compatible: compat +Version: 1.2.7i1 +Date: 1422287199 +Class: feature + +This new check allows you to monitor the average CPU utilization over all cluster nodes. +Each node has informations about the total available MHz and the actually used MHz for computing. +The actual usage of a cluster is calculated by the formula <i>(total_used_mhz / total_avail_mhz) * 100</i> + +Via WATO you can configure a set of WARN and CRIT levels for specific node counts. diff --git a/ChangeLog b/ChangeLog index ed3e6d1..de4d9a5 100644 --- a/ChangeLog +++ b/ChangeLog @@ -54,6 +54,7 @@ * 1857 ibm_svc_portsas: new check and extended special agent for IBM SVC / Storwize V3700 / V7000 devices * 1918 ps: new option for checking the age of a process (on Linux)... * 1920 df: Linux filesystem check now supports displaying data reserved for root... + * 1675 esx_vsphere_hostsystem.cpu_util_cluster: Averaged CPU utilization of all cluster nodes... * 1457 FIX: logins: new check renamed from "users" check...
