Nagios Support Forum

We have Nagios XI Enterprise 5.4.12 and I need to modify $ARG2$ and $ARG3$ across 1100 services (all bandwidth checks via snmp).

The services are pretty much identical... check command is check_xi_service_mrtgtraf, Command view is $USER1$/check_rrdtraf -f /var/lib/mrtg/$ARG1$ -w $ARG2$ -c $ARG3$ -l $ARG4$. The only thing that's different is $ARG1$ which contains the IP_portnumber.rrd

For example, one of these services is currently set to:

$ARG1$ 192.168.94.105_10101.rrd
$ARG2$ 5.00,5.00
$ARG3$ 8.00,8.00
$ARG4$ M

I want to change $ARG2$ to 500.0,500.0 and $ARG3$ to 800.0,800.0. I navigate to Bulk Modifications Tool -> Change Command and Arguments and modify:

Check command: <leave blank>
$ARG1$ <leave blank>
$ARG2$ 500.0,500.0
$ARG3$ 800.0,800.0
$ARG4$ <leave blank>

Select the 1 service to modify (as a test) then Save.

The problem is, both $ARG1$ and $ARG4$ get blanked out upon save.

Original command:check_xi_service_mrtgtraf!192.168.94.105_10101.rrd!5.00,5.00!8.00,8.00!M
Command when bulk modify used: check_xi_service_mrtgtraf!!500.0,500.0!800.0,800.0!

How do we only change $ARG2$ and $ARG3$ while preserving $ARG1$ and $ARG4$?

Thanks!

@darnorth, Yes, the bulk modifications tool overrides the whole command. Aside from modifying those ARG manually you could write a script that would: 1) copy services .cfg files from /usr/local/nagios/etc/services/ to /usr/local/nagios/etc/import/ 2) Modify the args with some kind of replacing command(like `sed`) and then apply the new configuration. Here's an example of the script: However, you need to be very familiar with sed command as if it could potentially mess up the other configs if you don't use it correctly. Please backup XI before you start.

Hi @npolovenko,

That worked great. Here's what I ended up using to change the values:

mkdir /backup
cp /usr/local/nagios/etc/services/* /backup
cp /usr/local/nagios/etc/services/* /usr/local/nagios/etc/import/
find /usr/local/nagios/etc/import/ -type f -exec sed -i "s/5.00,5.00\!8.00,8.00/500.0,500.0\!800.0,800.0/g" {} +
cd /usr/local/nagiosxi/scripts/
./reconfigure_nagios.sh

Thanks.

@darnorth, That's great! I will go ahead and lock this thread for you.
Thanks for using our support forum.
