Script to restart process

HI,

I am trying to write a scrip which would restart active process. This is what i have written till now.

Code:
[xmp@tswebptcadmin ~]$ xms show pr PRESE.*
NAME                            STATUS    ROLE  PID    RSTRTS  STARTED       MACHINE
-----------------------------------------------------------------------------------------
PRESENCE-STORE.1.tswebptcxmp1   Running   A     29002       0  Aug-27 20:58  tswebptcxmp1
PRESENCE-STORE.1.tswebptcxmp2   Running   S     16097       0  Aug-27 21:05  tswebptcxmp2
PRESENCE-STORE.2.tswebptcxmp1   Running   A     29003       0  Aug-27 20:58  tswebptcxmp1
PRESENCE-STORE.2.tswebptcxmp2   Running   S     16098       0  Aug-27 21:05  tswebptcxmp2

Code:
#!/bin/bash

ACTIVE_PSE_COUNT=`grep "Current number of Active Requests to the PSE" /home/xmp/bin/radstats_output.txt | awk '{print $NF}' | head -1`
ACTIVE_PSE_PROC=`xms show pr PRESENCE-STORE.* |awk '{print $3}'|grep "A"`

#Active PSE_COUNT
#-----------------
if [ $ACTIVE_PSE_COUNT -gt 200 ]; then
xms restart proc PRESENCE-STORE.1.tswebptcxmp1

fi

exit

Here if the value for ACTIVE_PSE_COUNT exceed beyond 200 then it should restart active process.

Here i want to restart active process which has value "A" under role, which i am not sure how to do it. Please advice.

Hi All,

Further to this.

Code:
#!/bin/bash

#########################################################################################################
# Shellscript   :       radiusmon.sh - Monitoring radius start/stop accounting
# Version       :       V1.0

#                       processes if reached threshold values
#########################################################################################################

#/home/xmp/bin/radstats > /home/xmp/bin/radstats_output.txt
ACTIVE_PSE_COUNT=`grep "Current number of Active Requests to the PSE" /home/xmp/bin/radstats_output.txt | awk '{print $NF}' | head -1`
ACTIVE_PSE_PROC_1=`xms show pr PRESENCE-STORE.1.* |awk '{print $1 $3}' |grep "A" |tail -1`

#Active PSE_COUNT
#-----------------
if [ $ACTIVE_PSE_COUNT -gt 200 ]; then
xms restart proc $ACTIVE_PSE_PROC_1

fi

exit

Now what issue i m facing is the out of ACTIVE_PSE_PROC_1 is as below...

PRESENCE-STORE.1.tswebptcxmp1A

I do not want the last letter "A" here, because of which it does not reastar the process. Please advice.

Code:
[xmp@tswebptcadmin ~]$ ./radiusmon.sh
ERROR: No such process: PRESENCE-STORE.1.tswebptcxmp1A

Hi

Code:
ACTIVE_PSE_PROC_1=`xms show pr PRESENCE-STORE.1.*  | awk '$3=="A"{print $1}' | tail -1`

you use an treatment on every line but you took only the first line. It's more logical to put the head -1 before the awk treatement. Moreover the grep has the option "-m x" which stop reading file when the x patterns are found.

so the code should be :
Code:
ACTIVE_PSE_COUNT=`grep -m 1 'Current number of Active Requests to the PSE'  /home/xmp/bin/radstats_output.txt | awk '{print $NF}' `

awk is a powerful tool, if you use a simple grep you must filter lines with awk :
For your code :
Code:
ACTIVE_PSE_PROC_1=`xms show pr PRESENCE-STORE.1.* |awk '$3 ~ /A/ {print $1 $3}' |tail -1`

Hi,

I got that working. Now the problem is

Code:
/home/xmp/bin/radstats > /home/xmp/bin/radstats_output.txt
ACTIVE_PSE_COUNT=`grep "Current number of Active Requests to the PSE" /home/xmp/bin/radstats_output.txt | awk '{print $NF}' | head -1`
ACTIVE_PSE_PROC_1=`xms show pr PRESENCE-STORE.1.* |awk '$3=="A"{print $1}'|tail -1`
ACTIVE_PSE_PROC_2=`xms show pr PRESENCE-STORE.2.* |awk '$3=="A"{print $1}'|tail -1`

/home/xmp/bin/radstats > /home/xmp/bin/radstats_output.txt

It is working fine when i run in shell prompt, and redirects the output to home/xmp/bin/radstats_output.txt. But in script it is just not working. Please advice.

In what way is it "not working"?

How is this shell script being run? Manually by you, or in cron?

Are you perhaps getting a different shell in the script than you do in your login?

sleep 30

if [ $ACTIVE_PSE_COUNT -gt 300 ]; then
xms restart proc $ACTIVE_PSE_PROC_2

As what user? Does that user have permission to write to that file?

Also, cron has a very minimal PATH. Add this just below the shebang: . /etc/profile which should get a more sane PATH set so it can find things like grep.
