Hello experts,
I'm trying to run a script that checks the processes listed and returns their name and their PIDs.
Code:
#!/bin/bash
PROCS="DMgr BPM.AppTarget BPM.Support BPM.WebApp BPM.Messaging nodeagent App.Messaging "
for p in $PROCS
do
PROCEXIST=$(ps aux | grep $p | grep -v grep)
if [ "$PROCEXIST" != "" ]; then
BPMPROCID=$(ps aux | grep $p | grep -v grep | awk '{print $2}')
echo "$p:PID $BPMPROCID"
fi
done
issue is that there are 2 nodeagent processes running and it just vomits the PID but doesnt really give the Name for the second Nodeagent.
Ideally , I would like the Node Name of the nodeagent also printed so you can differentiate amongst the nodeagents.
Any help is appreciated.
Look forward to your responses,
KK

I was using this but this stopped working since one of our processes has more than 4096 characters and processes were all wonky and incorrectly being reported by the script.
The issue is that you are echoing the value of $p after you assign the $BPMPROCID variable. The value of $p is hard coded in $PROCS list. What you would need to do is create a new variable in the same way you created $BPMPROCID to dynamically pick up the actually process name.
I am not sure where the process name (i.e. Nodeagent) gets outputted on the screen, but say if it is the last word on the line when performing 'ps aux' , the below amendments (assigning a PNAME variable and printing that instead of $p) should work for you. Hope this helps.

#!/bin/bash
PROCS="DMgr BPM.AppTarget BPM.Support BPM.WebApp BPM.Messaging nodeagent App.Messaging "

do
PROCEXIST=$(ps aux | grep $p | grep -v grep)
if [ "$PROCEXIST" != "" ]; then
BPMPROCID=$(ps aux | grep $p | grep -v grep | awk '{print $2}')
PNAME=$(ps aux | grep $p | grep -v grep | awk '{print $NF}')
echo "$PNAME:PID $BPMPROCID"
fi
done
Btw obviously Corona is right, there are of course more effective/efficient ways of doing this, I'm just trying to help to benefit your understanding at the very least.
Everything before the hyphen (-) like dmgr BPM.* nodeagent(Node1/2) is in the process its just that i suck this this whole thing.

I'm likely going to explain this clumsily, so apologies in advance:

I searched the forums but didn't see anything related to what I'm looking for. I need a script that would give me a listing of jobs running longer than, for example, 12 hours or so. Thanks in advance for your assistance!! (2 Replies)
