HTTP Probe

[stevedoyle]

How does the HTTP Probe function work ? Setting it up appears simple but it's not clear to me whether 1) the Local Director's will generate the probe traffic themselves or 2) do they just monitor return codes in client query's ?

If they're just monitoring client traffic, then a failed server may go unnoticed for some time if the file specified in the ProbeHTTP command isn't requested by a client for a period.

Also, aside from reviewing the syslogs, is there any way to see that it was the Probe which caused a server to change to a "failed" state ?

The ProbeHTTP commands appear in 4.2.1 but the functionality doesn't seem to work.

Are there known problems with this functionality in this release ?

I haven’t used http probe yet but the docs look like it probes either the http get or http header (depending on how it’s configured). I’m sure you can use this with snmp to avoid having to parse the syslogs. Or setup a script to do that for you.
