I'm having problems with the HTTP test.
Yesterday, I added additional URL's to monitor. We monitor a load of URL's, and yesterday, I added a lot.
After adding the additional URL's, I started getting Timeouts across the board. If I look at the graph for old URL's, it shows the graph increasing at the same time I implemented all the new URL's yesterday.
ie. I went from about 30 to 60 URL's.
Does Hobbit stager URL checks? Is there a way to stager them? I have a similar problem. I have +/- 200 netwerk tests (ping, ...) and +/- 20 http tests. All on local LAN. I added a second hobbit server on a remote connection (1mbps) and I had lots of timeout on the http checks.
Hobbit is doing per default 254 network checks in parallel. Let's say the first packet is 1 kbyte this means 254 kbyte/s. And I only have a 1mb(it)ps line!!! The solution was limiting bbnet to only 4 parallel checks --concurrency=4 to the bbnet start command.
Actullay, the strange thing is that there is a load balancer involved. So if
I do the remote check http and use the load balancer, I get +10 seconds.
Directly to the http server gives a normal result. This is only for the 254
parallel checks, 4 parallel checks and everything is normal.
