Every time a BoKS client becomes unreachable the master server will retain updates for this client in a queue. Over time this queue will continue to grow, containing all manner of updates to /etc/passwd, /etc/shadow and so forth. Without these updates the client will become out of date and known-good passwords will stop working. You could lose access to the root account if you don't keep a history of the previous passwords!
This simple Tivoli plugin will warn you of any client queues that exceed a certain size or age, with both thresholds adjustable from the command line.
./check_boks_queues [-m MESS] [-a AGE] [-d -o FILE] [-f FILE] -m MESS Threshold for amount of messages. Default is 40 messages. -a AGE Threshold for age of client queue. Default is 24 hours. -f FILE Log file that queues that are over threshold. Default logs into $BOKS_var. -d Debug mode. Provides error logging. -o FILE Output file for debugging logs. Required when -d is passed. The -a parameter requires BoKS 6.5.x. It DOES NOT work in 6.0.x and older versions. Example: ./check_boks_queues -m 50 -f /tmp/over50.txt ./check_boks_queues -a 168 -f /tmp/oneweek.txt
This script is meant to be called as a Tivoli numeric script. Hence both the output and the exit code are a single digit. Please configure your numeric script calls accordingly:
The log file in $BOKS_var (or specified with -f) will contain a list of queues that are stuck.
