|Title||Fixed degraded SNMP check performance when using SNMP sub checks|
|Check_MK Edition||Check_MK Raw Edition (CRE)|
|Level||2 - Prominent Change|
|Compatibility||Compatible - no manual interaction needed|
When checking a host with SNMP sub checks which normally all get the same data, the data was fetched multiple times. One time for each subcheck used for monitoring a host.
This resulted in significantly increased check times and time outs. All 1.5 versions are affected by this issue.
We experienced this issue with a CMCiii device which is normally monitored by a set of sub checks (cmciii.*).
