When investigating Avamar issues, it can be helpful to understand which activities were running concurrently when a particular event occurred.

The sched.sh script is a useful tool which can help to:
  • Identify what types of activities were occurring at the time of a particular event.
  • Get a visual representation of how backups, replication jobs, and maintenance activities are scheduled relative to one another.
  • Identify overlapping types of activity.
 
There are two versions of the 'sched' script: 
1. The original script: /usr/local/avamar/bin/sched.sh 
2. The sched function of the health check script (proactive_check.pl):
  
perl /home/admin/proactive_check/proactive_check.pl --sched
 

The output of the scripts is NOT identical, as can be seen below: 

Example output from sched.sh:

h=hfs, c=CP, g=GC, r=Repl, d=ReplDest, e=restore, uppercase means failed activity
A number is how many backups are running, 0=0-9, 1=10-19, b=100 or more backups
 
 
Interpreting the output:
  • The script produces a series of rows showing information for previous days (the --days flag determines how many).
  • Each row shows what happened from midnight (00:00hrs) to midnight (23:59).
  • Where more than one type of activity occurred at a particular time, an additional row shows how both activities ran concurrently.
  • A key at the bottom of the output explains the types of activity shown.
 
Note: One major difference between sched.sh and the proactive_check.pl --sched function is that the latter reports how many backups were running at a particular time. This can help to understand more accurately how busy Avamar was.
