Cacti Server Monitoring script for Unix

[rony]

Attached is a monitoring script for monitoring the cacti server.

What the script monitors:

• httpd is running or not running
• mysql is running
• if mysql is a replication slave, that it is currently up to date
• that the Cacti poller is running
• that the Cacti log is not to large
• that the mounted volumes are not filling up

Just add this to your crontab for either root or the user that runs the poller every 5 minutes or the same interval you run the poller.

If you find any issues, please let me know either here or via pm/email.

Hi sounds nice but when i edit the path en run i get the following error any ideas?

linux:/bin # ./cacti_monitor.sh
: bad interpreter: No such file or directory


Thanks in advance,

Marcel

Edit the first line of the script and alter it to use bash.

To find the full path to bash use the `which bash` command.

It's designed to work with bash, so if you don't have bash installed, I suggest you do.

Thanks for your reply.

these are the first lines in the monitor file:

#!/bin/bash
###############################################################################
# +-------------------------------------------------------------------------+
# | Copyright (C) 2006 The Cacti Group

when i perform a search for bash i get these results:
linux:~ # find / -name 'bash'
/bin/bash
/usr/share/doc/packages/bash
find: . changed during execution of find


Can you tell me what to change? do i need to uncomment the first line?

Thanks in advance.

[rony]

Nope, you probably need to change the permissions on the script to rwx for that user you are going to run it as.

Use the following to change the permissions:

Code: Select all

chmod 755 cacti_monitor.sh

Make some screenshots.
We like screenshots.

Screenshots of what? The outputted alert email?

There is no graphical parts to this, it's a shell script that does some basic system checks.

Version 1.01 posted in the first post.

Minor update to fix false positives when the cacti.log file is empty after being rotated.

Nice script........looks awesome. I was testing on my system and got an error when shutting down httpd...I get an error on line 313 where mail is listed..........is that piece of code that actually mails out?? what is required there to have the mail portion work?

Do the following commands and report the results:

netstat:/home/cacti# which mail

[rony]

Not sure what package has it but you need to install the mail or mailx utility.

[spoonman]

Thanks Tony...just needed apt-get install mailx
