My Hobbit server does the display, network testing and alerting. Using the default 5 minute interval for network tests. Some have complained that connectivity tests to certain routers should happen more frequently. But, as far as I can see, network testing interval is an all or nothing variable. So I'm thinking of setting up second network tester and using NET variable in bb-hosts to have the particular routers in question tested by second network tester, running its tests more frequently.

Preamble done - now, how do I go about setting up second network tester? Configuring another server and disabling all unnecessary tasks in hobbitlaunch.cfg? If so, which will I need for the tester to work properly?

You don't have to setup a different Hobbit server, if your current server has enough capacity to run the network tests. E.g. use this script "netchecks.sh":

#!/bin/sh

BBLOCATION=$1 bbtest-net --report=bbnet-$1 --ping --checkresponse exit 0

Then in your hobbitlaunch.cfg you have two (or more) entries:

[net-std] ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg CMD netchecks.sh standard LOGFILE $BBSERVERLOGS/bb-network.log INTERVAL 5m

[net-frequent] ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg CMD netchecks.sh frequent LOGFILE $BBSERVERLOGS/bb-network.log INTERVAL 1m

This runs two sets of network tests - one with 5 minute intervals, the other with 1 minute intervals. Then in bb-hosts, flag each host with "NET:standard" or "NET:frequent".

Thanks -

Looks like an excellent solution for now. But I would still like to learn how to set up a second network tester. Due to recent merger and other situations, it looks like we will be adding a large number of machines to be monitored and I worry about capacity
