Database | Filesystem | CPU Monitoring Script

Database | Filesystem | CPU Monitoring Script

I would like to share with you today the dbalarm.sh script. This script monitors FILESYSTEM usage, CPU overhead and report ORA- errors and TNS- errors on ALL databases & Listeners ALERTLOGs on the server.

This script is coded to send you the new errors that appear since the last script execution,
in other words, it will not report the already reported errors unless they get logged again in the logs, and this is one of the key strengths of that script.

This script has been tested on Linux and SUN environments.

How to use dbalarm script?

========================

This script is very smart and very easy to use, just follow these three steps:

Step 1:

Download the script from this link:

https://www.dropbox.com/s/5gl4w1dz5zgawsw/dbalarm.sh?dl=0

Step 2:

Open the script and change the E-mail address to your email address in the line# 22

MAIL_LIST="youremail@yourcompany.com"

Note: sendmail service should be configured and running on your server.

Step 3:
By Oracle user:

Schedule the execution of this script in the crontab at least every 5 minutes:

# crontab -e

#Add this line to schedule the run of dbalarm.sh script every 5minutes:

*/5 * * * * /home/oracle/dbalarm.sh

Note: /home/oracle/dbalarm.sh is the full path pointing to dbalarm script where /home/oracle is the Oracle user home directory.

In case you will schedule this script to run from root user crontab:

# crontab -e

#Add this line to schedule the run of dbalarm.sh script every 5minutes:

*/5 * * * * su - oracle -c /home/oracle/dbalarm.sh

Now the only thing remaining is to set back and relax and the script will send you the errors once it appear.
