I have been battling false alerts with hobbit for quite some time (months or more), and am really starting to get quite frustrated. (Mostly in that I tend to ignore my SMS messages because there are so many FP's...
Anyway, the fault is that the hobbit client reports get truncated, yet the hobbit server uses the portion that it gets. This usually results in the procs, ports, or both columns going red due to non-running procs/non-open ports. In reality, the proc/port is fine, just the data was truncated so the hobbit server couldn't find it.
Initially I discovered my hobbit server was truncating some of this data, so I increased the relevant variables: MAXLINE="65535" MAXMSG_STATUS="2048" MAXMSG_CLIENT="2048" MAXMSG_DATA="4096"
However, I still get many red alerts, and when I check, the log files do not report any truncated or oversized messages. Also, when I examine the "Client data available" from the red hobbit report, I find the size of the message is nowhere near any value above, and in fact is always different... Some reports that work are longer than reports that don't work etc...
It isn't 100%, but generally (more than 98%) the clients with the problem are on bandwidth limited networks.
I would appreciate if anyone can provide any tips on how to make things more reliable?
Options I have considered:
- Get hobbit to compress it's data, which reduces network load, and hence should improve reliability.
- Add a "END" tag to the hobbit client data, and if the server doesn't get the END tag then ignore the whole file (or re-request it)
- Switch to polling mode (which effectively does 1 && 2 I suppose)
- Try and track down what is causing this, and fix it...
My hobbit server is behind a NAT router, so one possibility I have considered is the NAT router is dropping the map before the end of the TCP connection due to too many other connections or similar.
Basically, at this point I would like to see if anyone else has had similar problems, or can assist in resolving the problem. If I let it continue I will miss an urgent SMS report from hobbit, and/or cost stacks of money for sending all the SMS's....
Thanks for any suggestions...
