Nagios Support Forum

I am just using Nagios XI to check if a file is being updated every 30 mins
also I have tried to use the config wizard file age but it does not seems to be working
please see attachment

Hi @DOkuwa,

Please look at the command usage below your is not defined well.

Please parse arguments in the correct order.

please can you give an example

-C 'ssh nagios@$HOSTADDRESS$ ls -lA /opt/InCharge/DEV-OI/smarts/local/logs/' -F 'Heartbeat.log' -r

usr/local/nagios/libexec/folder_watch.pl -C 'ssh nagios@$HOSTADDRESS$ ls -lA /opt/InCharge/DEV-OI/smarts/local/logs/' -F 'Heartbeat.log' -r -a 60,120 -f
UNKNOWN ERROR - execution of ssh nagios@$HOSTADDRESS$ ls -lA /opt/InCharge/DEV-OI/smarts/local/logs/ -R resulted in an error 65280 -

When running this on the command line the $HOSTADDRESS$ should be replaced with the IP address of the remote server. For example:
If you haven't already, follow https://assets.nagios.com/downloads/nag ... ng_SSH.pdf to create keys for the nagios user and transfer them to the remote system. There must be a nagios user on the remote system as well in order for the connection to be made.

thanks a lot it worked but
I want to check my file Heartbeat.log to see if it is updating
what argument do I use and the please send the full command

yes Nagios user is already on both server and check_ssh module has been on the client


/usr/local/nagios/libexec/folder_watch.pl -C 'ssh [email protected] ls -lA /opt/InCharge/DEV-OI/smarts/local/logs/' -F 'Heartbeat.log' -r -s 100,130 -f
CRITICAL - Heartbeat.log is 20203 (more than 130) bytes - 1 Heartbeat.log files found | 'Heartbeat.log'=1 size_largest=20203B;100;130;;; size_smallest=20203B;;;;;

but I still need the command to indicate that the Heartbeat,log has been updated
if it has not been updated send a warning or critical message if it has been update it is ok

This will check and alert if the file size is 20203:

Thanks
it works
but I maybe a bit specific here
every morning there is rolllogs here and all logs are 0k in the morning ( I mean file size is 0)
I want to know if I can use a find command to see if there updates very 30 minutes in a file in a directory and report critical If there is nothing and ok if there is
e.g find /xxxx/xxx -type -f -name xxxx.log -mmin +30

There are over 4250 plugins on exchange.nagios.org, and plenty on github that never make it to our exchange. None of the techs have exhaustive knowledge of what is out there. The best thing to do is just look on exchange.nagios.org and in your favorite search engine and see if you can find a plugin that does what you want. If you can't find something, then you will need to write it. If you set out to write your own plugin, please take a look at https://nagios-plugins.org/doc/guidelines.html

Alternatively, we offer custom development and consulting for a fee.

That said, if you log the size at each check, and set a check to run every 30 minutes, it would seem like it wouldn't be that hard to get what you want.
