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".

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

This reminded me of something. When setting up the ENV var BBLOCATION, that seems to really annoy bbhostgrep. If I have any ext script that makes use of bbhostgrep, I had to unset that variable for things to work right. Not sure if this is a bug, I haven't seen anyone else encouter this.

Just the bbnet and bbretest tasks (and, maybe hobbitfetch if applicable), and the hobbitclient task if you want the second network tester to report as a client.
