Update in script not visible in performance graph

[nms]

Hi all,

Basically I have a script with the following output:

“Total CCS_HPLMN_MO_TMNL OK - 4682 | CCS_HPLMN_MO_TMNL=4682; “

The performance graph in Nagios XI works perfectly graphing the part "CCS_HPLMN_MO_TMNL=4682;"

I then modified the script to give us more outputs in the graph as follows:

“Total CCS_HPLMN_MO_TMNL OK - 4682 | CCS_HPLMN_MO_TMNL=4682; High=5446; Low=3630;”

I expected that the performance graph would have changed a few minutes after, but it was still stuck to the first one. The only thing that was updated were the gauges.

It seems the only way was to completely remove the service and add it again or else rename it.

Is there another way of making this work without losing the performance graph history?

Rgds,

The following KB article is a procedure you can use to update performance graphs when the the performance data points are changed.

Hi

Thanks. The article is correct, but it seems there are issues in installing the perl RRD:Simple package. I tried also with cpan

Code: Select all

cpan YAML cpan RRD::Simple

but am running into issues. The installation is on a CentOS release 6.9.
RRD tool has been installed successfully

What is the output when you run the following commands?

Code: Select all

yum install perl-RRD-Simple -y
cd /tmp
./fix_ds_quantity.sh -d /usr/local/nagios/share/perfdata/

Hi,

There's nothing available for RRD:Simple:

Then still tried to run it (or just to see the output)

Code: Select all

This script will add datasources to RRDs.  It may require
up to 3x the current disk space used by the rrds that need
updated.  Please make sure you have enough free space to
run this script.

This makes changes to your RRDs, so DOUBLE CHECK that you
have made a recent backup of the RRDs.

This script can take a long time to run (1h+), so it may
be best to run it during maintenance.

Are you sure? (y/n) y

As you can see Simple pm is not found, although it seems that it still tried to fix the datasources. However there were no changes, i.e graph did not update with the additional performance data

Instead of using yum to install the RRD Simple module, lets see if the cpan utility can do it.
Run the following as root

Code: Select all

cpan -i RRD::Simple

If it installs then run the fix_ds_quantity script to see if it updates the graphs for you.

Code: Select all

cd /tmp
./fix_ds_quantity.sh -d /usr/local/nagios/share/perfdata/

Hi tgriep,

Yes have tried cpan, but it seems there are prerequisites that won't install. Have attached the output since it's exceed the max allowed.

cpan - RRD Simple.txt

[tgriep]

Lets see if you can force the install of the perl modules, run the following as root.

Code: Select all

cpan -f -i IPC::Cmd
cpan -f -i Module::Load::Conditional
cpan -f -i Module::Metadata

If they install, try installing the RRD::Simple module again.

Code: Select all

cpan -i RRD::Simple

If more modules are missing, go ahead and install them and repeat the RRD::Simple install.
