Memory Usage Graph Issue

[Berto]

Here is the requested output:

Memory: 16G phys mem, 1329M free mem, 25G total swap, 25G free swap

[ssax]

Please edit the plugin and around line 105 change these two lines from:

Code: Select all

total=`echo $topout | awk '{print $2}' | sed -e 's/M$//'`
free=`echo $topout | awk '{print $5}' | sed -e 's/M$//'`

To:

Code: Select all

total=`echo $topout | awk '{print $2}' | sed -e 's/\(M\|G\)$//'`
free=`echo $topout | awk '{print $5}' | sed -e 's/\(M\|G\)$//'`

Let us know if that resolves the issue for you.

Well here's probably a stupid question but I assume the plugin would be check_mem? If not what then? I used the Solaris wizard when configuring and when I go to where the plugins are, I don't see anything that looks like checking memory.

The plugin should be installed on the Solaris server and it's location is here

Code: Select all

/opt/nagios/libexec/custom_check_mem

That is the plugin that has to be edited for the check to work.

I edited the plugin and this is what the output was. I also disable/enabled NRPE on the Solaris server before trying the plugin again.

solarishost# /opt/nagios/libexec/custom_check_mem -w 30 -c 10
/opt/nagios/libexec/custom_check_mem: line 104: 16G: value too great for base (error token is "16G")

Please attach your modified plugin, it doesn't look like it was modified.

I have uploaded the plugin but had to add a .txt to the end for it to be upload.

--Berto

[ssax]

Apologies, sed works differently on SunOS, please replace them with this:

Code: Select all

total=`echo $topout | awk '{print $2}' | sed -e 's/G$//' -e 's/M$//'`
free=`echo $topout | awk '{print $5}' | sed -e 's/G$//' -e 's/M$//'`

Let us know the results.

[Berto]

That seems to have fixed it as I now get;

/opt/nagios/libexec/custom_check_mem -w 30 -c 10
OK - 1222 / 16 MB (7637%) Free Memory, Used: -1206 MB, Shared: 0 MB, Cached: 4451 MB | total=16MB free=1222MB used=-1206MB shared=0MB cached=4451MB

So my next question then would is there a way to update the wizard for any future installs on Solaris servers?

--Berto

[ssax]

Which wizard? Are you talking about the linux-nrpe-agent.tar.gz file that you download and install?
