I'm using Hobbit to monitor the availability of the routers and at this moment I'm using a standard mrtg setup to get data. To show data got with mrtg I'm currently using routers2.cgi, a simple perl scripts that will let you manage the visualization of data on the page (you can group routers by site or some other mechanism). You can find it at http://www.steveshipway.org/software/ it's simple to setup and really fast. The setup is simple, I'd wrote some scripts to do some thing in automatic, mostly:
- One script that run during the night and via cfgmaker (standard mrtg script) create one mrtg.cfg file for each device i want to monitor and create history archive.
- one script that run from hobbit every 5 minutes, get the list of all the cfg file I'm monitoring and launch mrtg with that cfg file (I need cfg files because in the past i got some problems with mrtg exiting when one error was found)
- A script that simply send a green status to hobbit for each monitored hosts and inside that status message i've put a simple javascript that open a popup page that point directly to the routers2.cgi to open that page....
The nice thing of routers2.cgi is that he can save an archive of all your rrd file mantaining for example the 7 rrd (so you can check up to 7 day of full data), the last 4 rrd of the 1st of the month data (so you can check and compare data of each month). You can also archive single graphs, create a pdf report, do a trend statistical report to see how the usage of network is going in the next few months based on istorical data or you can directly export the data of a routers to csv file and open it with your spreadsheet to analyze what happened.
It's snmpv2 compliant so no problems with gigabit interface and with cfgmaker you can automatically create the configuration file you need.
There's no automatic setup so you've to create some scripting yourself but the results are good and most of all you've some really well made summary page where you can see all the interface of a router or you can create some custom graphs with the data you need ...

We have 14 remote sites (manufacturing facilities and distribution warehouses) with an average of 5 Cisco switches each. We've been using cricket to monitor the traffic on these switches, but cricket is doing a number on the cpus of the system I'm running it on. And I've never figured out how to get cricket and hobbit to integrate for alerts.
I just dropped devmon on my test system, and I really like the integration -- but it looks like it's doing a number on my test system cpu, and we do use the traffic graphs out of cricket to see trends.
So -- is cacti any lighter in it's footprint? Or easier to keep up-to-date than cricket? Does it integrate well with hobbit?
Should I be looking at something else?
My current hobbit system is an ancient (as technology goes) Dell 4300 4-way P4 - 450 system with 1 GB of memory; my test system is a slightly newer Dell 2300 2-way P4 - 500 with 512 MB of memory.
Suggestions, please.
TIA
