Linux agent installation for VM monitoring

gauravm07 · August 2021

Hi Team,

I wanted to monitor and test one of my SuSe linux server via lpar2rrd. I have installed "lpar2rrd-agent-7.20-1.noarch.rpm" and configured Perl script in crontab.
Though script runs fine as I see files and output getting generated under /var/tmp/, data is not getting populated on lpar2rrd web interface.
Any suggestion on this or am I missing something in this approach.

Hi,

date

ls -ltr /var/tmp/lpar*

tail /var/tmp/lpar*err

gauravm07 · August 2021

Please find below details.
I have followed below link and see all output is fine, starting from client to lpar2rrd server.

https://www.lpar2rrd.com/Linux-agent-install.php#OSagent

only other observation is, on lpar2rrd server, data is populating under below path and is getting updated every 15 mins but I cannot see linux tab/server under Graph UI

Hi,

is stnsvpeadb201 a VM runing on VMware or any other virtualisation platform?

Do you monitoring that virtualisation platform via lpar2rrd? You should see that data under that platform in the lpar2rd menu, pls check

ls -l /home/lpar2rrd/lpar2rrd/tmp/menu*

grep stnsvpeadb201 /home/lpar2rrd/lpar2rrd/tmp/menu*

grep stnsvpeadb201 /home/lpar2rrd/lpar2rrd/logs/daily*

Hi Pavel, stnsvpeadb201 is a VM running on VM. we are trying to direcly send data from VM to lpar2rrd UI via agent.

is hostanme stnsvpeadb201 same as the VM name?

gauravm07 · August 2021

Hi Pavel, yes both are same. Any other output or config we need to check

Pavel · August 2021

Do you monitor that VM via virtualisation management station (like VMware, Hyper-V, RHV ...)

Pavel · August 2021

I mean monitor it via lpar2rrd

gauravm07 · August 2021

Hi Pavel, no we don't monitor VMWRE via lpar2rrd.

Pavel · August 2021

send us logs

Note a short problem description in the text field of the upload form.

cd /home/lpar2rrd/lpar2rrd # or where is your LPAR2RRD working dir

tar cvhf logs.tar logs tmp/*txt tmp/*json

Hi Pavel,

Any update by seeing the logs submitted

Jindra · August 2021

Have not you got direct email we sent you 23/08 ?

gauravm07 · August 2021

Hi Jindra, I did not receive the email, can you re-send it.

Thank you

Jindra · August 2021

Hi Gaurav

sent again

gauravm07 · August 2021

Hi Jindra,

Not sure but I am unable to see the email. just confirming that it is been sent to gaurav.mishra@nutrien.com

gauravm07 · September 2021

Hi Team, Can you please check and update please.

Jindra · September 2021

Hi Gaurav,

the linux machine was before some time under vmware, that is why it is not taken to Linux menu

Here is hot fix

Keep the original script "bin/find_active_lpar.pl" in backup

https://download.lpar2rrd.com/patch/7.21-8-4-gd000/find_active_lpar.pl.gz

Gunzip it and copy to /home/lpar2rrd/lpar2rrd/bin (755, lpar2rrd owner)

-rwxrwxr-x 1 lpar2rrd lpar2rrd 88888 Jul 21 09:06 find_active_lpar.pl

If your web browser gunzips it automatically then just rename it: mv find_active_lpar.pl.gz find_active_lpar.pl

Assure that file size is the same as on above example

Either wait till next day, the change in menu will come automatically or from cmd line:

su - lpar2rrd

. /home/lpar2rrd/lpar2rrd/etc/lpar2rrd.cfg ; $PERL ./bin/find_active_lpar.pl

./load.sh html

Refresh your gui

Let us know

gauravm07 · September 2021

Hi Team, I tried above steps but still VM is not populating and graphs are not showing up. Any logs to be captured to check further?

Gaurav Mishra
