@remh have you seen this before? CPU seems busier than it should be, on top of not getting the data.

The cpu must be rising because the jmx connection is not working. So at each collection the agent spawns a new jmx connector process, launching the jvm which may be cpu consuming.

What's happening when we manually launch jmx connector ?
java -jar /usr/share/datadog/agent/checks/libs/jmxterm-1.0-DATADOG-uber.jar -l localhost:8090 -u USERNAME -p PASSWORD
Is the connection working ?

Independently from knowing why the connection doesn't work, we need to
guard against behaviors that end-up consuming tons of CPU. Should we add
some back-off when that happens? What status does the agent report?

An easy-ish way to limit our cpu is to nice the process when we run it so that our cpu usage gets deprioritized.

Yep, that's a start.
Seems like spawning tons of new outside processes with immediate failure
could have a number of nasty consequences, though. Wondering if it would
make sense to add a utility into the agent core for handling back-offs /
giving-up and reporting of these situations.

Ok so here the things I did:

  1. When the connection fails 3 times in a row, we won't try to open it up again.
  2. The jmx process will be launched with nice -n 15
  3. I added an option in the jmx terminal to do a prefiltering of the values that are fetched which seems to add more stability to the jmx connector
  4. Better failure handling
  5. The check will only dump jmx domains that are actually used

Performances are ok but not great, the jmx connector uses a mean value of 2% cpu on my machine, with high peak when performing the dump. Collector is ok (less than 0.5 %)

In the overall, it will fix the problem encountered. I used ab to apply heavy load to a tomcat instance and it seems to be working as expected, although from time to time the jmx connection breaks without an obvious reason, but the improved failure handling will relaunch the connection at the next collection.

How many concurrent connections did you use with ab?

200, I couldn't get more

Worth spawning a big ec2 box to crank that number up. 5000 is a good
target.

JMXFetch is going to be way more efficient.
