How to find a host from a list of hosts in a file?

[gokulakrishnans]

I need to refer to a table file which contains a list of servers. Need to check with all the servers like a loop which shows the status as 200-Means success/OtherErrorCode-Unsuccessful.

If any of the servers in the list is having other than 200, then an alert should be triggered.

Use a subsearch.

index=foo status!=200 [ | inputlookup serverList.csv ] | ...
