Help with Monitoring script
Hi Gurus,

Currently I am learning UNIX through online forums and unix blogs. I have the below requirement.

I need to write a script to monitor server processes. For example, there are 3 processes currently running on the server.(java, pmrepagent, pmserver). If any of the process goes down, then i need to send out an email to the user.I am trying to achieve this by using ps -ef | grep info command. when I execute this command, i get the information about the above processes. Now I need to look for the above 3 processes and if any of the process is not displayed in the information which i got from the command, then it should send out an email. I need to run this scrip in every 10 mins. I have started writing the script then I am not able to complete the script. Please help me with this.

Code:
#!/bin/ksh
get_process=`ps -ef | grep info > process.out`


Below is the output from process.out

Code:

the way which you are following is error prone.

try to use monit which is more promising than your current method.
