RE: [hobbit] scalability of hobbit/xymon ?

["T.J. Yang" <tj_yang (at) hotmail.com>]

To resolve this issue of unknown capacity, I think we need to come up a test/torture script for xymon hobbit server. This way we can demonstrate/simulate the load capacity of xymon server before deployment.


I have some idea on how to do the coding(using perl's test module), it will be great if your company can allocate resource to do this programming task together. otherwise I am interested to do it myself but a lower priority.

In large networks where you need to monitor hundreds or thousands of hosts, processing of the data simply cannot keep up. Another problem with BB is that it stores all status-information in individual files; when you have lots of hosts and statuses, the amount of disk I/O triggered by this severely limits how many systems you can monitor with one BB server.
