Sites with poor connections generating UNKNOWN alerts

Hi all, I have two remote sites connected over VPNs that have poor internet connections. The behavior I'm seeing from Nagios is that the Ping check to the server's IP remains up but the service checks periodically time out generating UNKNOWN status alerts for all the checks on that server, they reco...

Checking Shadow Copy Status on Windows Servers

Is there an easy way to check a windows server to see if it's shadow copies are enabled. The VSS service only turns on when it's in use so I can't just check the service. I typically use NCPA for all my checks.

Re: Windows server CPU monitoring discrepencies

I upgraded a few of the offending agents to 2.1.1 but they still create the same behavior, just maybe a little less often. Most of these servers are low utilization servers, backup DCs, a lightly used application server and secondary file servers. All of our high-utilization servers are reporting ut...

Re: Windows server CPU monitoring discrepencies

I just noticed something odd that may relate to this issue. When I view the performance graphs for CPU usage I can see the usage spikes up to 100% on several servers at the 4 hr, 24 hr, 7 day, and 30 day intervals. When I go out to the 365 day interval I do not see as high of a spike, they only appe...

Re: Windows server CPU monitoring discrepencies

So we have several servers that are showing different levels of CPU utilization. Our backup DC, which is virtualized and has 4GB RAM and 1 3.07 GHz vCPU, CPU usage goes from near zero to 100% very frequently, but sometimes stays maxed out. On the server itself the performance counters show near zero...

Re: Windows server CPU monitoring discrepencies

I updated the check_ncpa plugin and the client on two of the servers exhibiting symptoms, but no luck. Nagios continues to report the server CPU utilization going to 100% for about 5 minutes then dropping down to nearly zero for 5-20 minutes, but the server's internal performance counters show nearl...

Re: Windows server CPU monitoring discrepencies

No changes have recently occurred to either the targeted servers or the Nagios server. The version of NCPA agent is 2.0.2. The check I'm running is the following: check_xi_ncpa!-t 'nagiosncpa' -P 5693 -M cpu/percent -w 50 -c 80 -q 'aggregate=avg' It checks every 5 minutes and rechecks every 2 minute...

Windows server CPU monitoring discrepencies

We have been using Nagios to monitor our mostly windows server environment. Up until about a month ago I was able to understand and tune my alerts to match our network's baseline but a few weeks ago several of the servers started reporting steady increases in %CPU utilization. When I investigated th...

How to handle monitoring groups of services on a server

This is more of a recommended procedure than a technical question When you have a large number of services on one server you need to monitor does it make more sense to just add them each individually or create a remote script that triggers to check them all and returns a good/critical/warning/unknow...
