I was playing around with the check_route plugin and noticed a few issues with it not running. In order to get it to work on my Opsview boxes I had to install a new package, change some settings on the traceroute program and then make a patch in the script itself.
First thing you need to do is download the traceroute package if its not already installed
|
1 |
sudo apt-get install traceroute |
Once installed you will find that the plugin will fail and show the following error:
|
1 2 |
The specified type of tracerouting is allowed for superuser only Can't use an undefined value as an ARRAY reference at ./check_route line 129. |
Googling the first line I found that you have to setuid root for the traceroute binary
|
1 |
chmod u+s /usr/sbin/traceroute |
Trying the plugin again you get the following error
|
1 2 |
Use of uninitialized value $time_units in string eq at ./check_route line 114. ROUTE UNKNOWN - Cannot cope with line 'traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets' |
To get around this you need the plugin to ignore the first line of the output from the traceroute which can be done with the following patch
http://snipt.net/mattywhi/opsview-check_route-diff/
Now the script runs as expected and you get the following output
|
1 |
ROUTE OK - Time taken is 145.895 ms | total_time=145.895ms;5000;100000 hops=14;; route_change=0;; |
Would you be able to repost the link to the script change to “ignore the first line of the output from the traceroute”?
Many thanks.
