Looks like performance data shows more meaningful info about the uptime. How do I include this details in the email alert?

I suspect there is some bug or 32bit counter limitiation or something like that going on. From what I can gather it's reporting "how long it has been up for" AND "greater than critical threshold". Like in this example:

CRITICAL: uptime: 4w 1d 2:9 > critical|'uptime'=2513363000;0;2419200000

What version of NSClient++ are you using?

The developer has added an additional uptime check in the later versions, it's called Check_Uptime.

Command:
check_nrpe -H win2008r2-01 -c Check_Uptime -a 'critical=uptime>7d'

Output:
CRITICAL: uptime: 4w 4d 23:1h, boot: 2015-Jul-02 04:24:40 (UTC)|'uptime'=2847701s;172800;604800

It still doesn't say why it's critical, like "critical threshold of 7d exceed by xxx".

Thats kind of complicated. Either you adjust the email template in XI which will send the performance data with all notifications OR create a wrapper script that discects the returned data and does additional calculations on that.

I suggest going to the NSClient++ forums and ask what is going on and why and how to improve it.

We're on a very old version of NSCLient++ - 0.3.8.76

Thanks.

You should update to a modern version. Bugs are very often found and resolved in that software. The newer versions have some syntax changes in the config file, I would suggest changing now instead of later as it will ultimately be less work for you.

Update the client or both client and server? Updating the server might require more work I would think.

Just the client.

So just to confirm that the latest client will work with older version of server?

Yes, the server (XI) and client (NSClient++) have no dependencies on each other. The communicate using common protocols.

Just did a manual upgrade to latest client and I can see number of extra lines have been added to NSC.ini in the new version;
SysTray.dll=
FileLogger.dll=
CheckWMI.dll=
CheckSystem.dll=0
NSClientListener.dll=0
CheckHelpers.dll=0
CheckEventLog.dll=0
CheckDisk.dll=0
CheckExternalScripts.dll=0
CheckNSCP.dll=0
NSCAAgent.dll=0
NRPEListener.dll=0

Do I need to be concerned about the above?

And as expected, most of the services cannot fetch information from the server after client upgrade. I can only get a ping service to work. I suspect that nsc.ini will need a bit of work? I get connection refused on all of the windows services after running monitoring wizard.

Thanks.
