[Spacewalk-list] Query current OSA clients

[Justin Edmands]

Hey Spacewalkers, 
I am attempting to query all of the systems that are currently checking in via OSAD. I have been using a fairly inefficient spacecmd command to make this work for now. 

[12:00:13][justin at justindev1:~]# spacecmd system_details S0* | grep -e "Name" -e "OSA" >> OSA_status.out ; grep online OSA_status.out | wc -l 

the S0 just happens to be the first two characters in the names I want to query. In the end it does a word count to determine how many are "online" 

Any better way to do this? This takes about 2-5 minutes when run against a list of about 500 clients.
