performance graphs not showing warning and critical lines

[sampaths]

Hi,

We recently upgraded from Nagios XI version 5.2.9 to 5.5.9 on our test server.

Previously we were able to see warning and critical line in the performance graphs.

Right now in version 5.5.9 we are not seeing that.

please advice, how to enable them.

The warning and critical values have been removed from the "popup" after XI 5.3. Also, the warning and critical lines would show on the graph only if you had one datasource. If you had multiple datasources, the line wouldn't show at all.

what is multiple datasources?

Here is how we are running the check.
root@hadcrdtnagios01:~# /usr/local/nagios/libexec/check_nrpe -H HQBISQL80N1 -c CheckMEM -a ShowAll type=physical MaxWarn=95% MaxCrit=97%
OK: physical: Total: 31.994GB - Used: 29.516GB (92%) - Free: 2.479GB (7%)|'physical'=29.51562GB;30.39445;31.03433;0;31.99416 'physical %'=92%;95;97;0;100
root@hadcrdtnagios01:~#

this is a windows server running NSClient++
here is the graph for it.

Well, you have two datasources in this check - 'physical' and 'physical %'.

OK: physical: Total: 31.994GB - Used: 29.516GB (92%) - Free: 2.479GB (7%)|'physical'=29.51562GB;30.39445;31.03433;0;31.99416 'physical %'=92%;95;97;0;100

You can see both in the graph.

Here's an example of a check with one datasource in the output:

/usr/local/nagios/libexec/check_nt -H x.x.x.x -s "password" -p 12489 -v USEDDISKSPACE -l C -w 90 -c 95
C:\ - total: 107.47 Gb - used: 87.85 Gb (82%) - free 19.62 Gb (18%) | 'C:\ Used Space'=87.85Gb;96.72;102.10;0.00;107.47

You can see the warning and critical lines on the graph.

We are using check_nrpe, i cannot change all my checks to check_nt now

I am using exactly how it is defined here.
https://support.nagios.com/kb/article/n ... l-169.html

in every implementation of check_nrpe to check memory has both 'physical' and 'physical %' according to this page.
https://support.nagios.com/kb/article/m ... s-774.html

removing data from popup is ok but not able to plot graphs if there are multiple datasources which used to work before, i see this as a feature loss for us if we upgrade to latest version.

or if i am missing something please let me know a way where i can continue using check_nrpe and just get one datasource.

@sampaths, This is the performance output from your memory check:

'physical'=29.51562GB;30.39445;31.03433;0;31.99416 'physical %'=92%;95;97;0;100

Graph #1 is called 'physical'(its value is roughly 29) and graph #2 is called 'physical %'(its value is 92%).

So since there are 2 graphs in 1, where would the threshold line be? At 97% or at 30(which roughly equals 97%)?

You'd say it makes sense to only include the percentage graph to draw the threshold line in this case. But what about graphs with multiple measurements, like this one? It'd be impossible to figure out where to draw the threshold line.

That's why the decision was made to only draw a threshold line on graphs where there is only 1 measurement=datasource.

All graphs will still work regardless of how many data sources, but the threshold line will not be shown.

[sampaths]

ok I understand, could you please guide me how to use check_nrpe (we don't want to use check_nt) when i have a nsclient++ running on a windows machine.
And monitor for memory check, with only one data source in the output so that we can have the lines for thresholds in the graph.

@sampaths, Consider using the following command + syntax instead:

/usr/local/nagios/libexec/check_nrpe -H HQBISQL80N1 -c check_memory -a 'warn=free<5%' 'crit=free<3%' 'type=physical' "perf-config=*(ignored:true) %(ignored:false)"
