[smokeping-users] Re: Some graphs stay empty

[Dan McGinn-Combs]

Ralf,
>From a troubleshooting point of view you need to know whether your problem is the measurement tool (fping or echoping) causing the problem or the rrdtool update and graph. 
Sorry I missed previous messages, but I think you said you were using http. What I would do is emulate the call to echoping using the command line. This will tell you if echoping is working or not.  If you are using fping you should to the same thing. I dont have my computer on, but the man pages should give you an idea of the appropriate command lines.  

Second, if these are working (i.e. You get back reasonable responses) then check the rrd updates by checking the time and trying a manual update. The command line version of rrdtool should give you some indication as to why the update isn't working.

If that doesn't cut it then perhaps the graphing isn't working. Again try to manually built a graph for the last 24 hrs. 

Finally use "rrdtool info" at the Command line to check that the db meets criteria for a successful update and graph (that is Compare the last update field to the RRDs that do show a graph).

Good luck 
Dan

    Come on, we had this. I can ping it, http it, ssh it, whatever it.
    (You can't, it's hidden behind the firewall from the evil internet).
    
    I need more debugging folks. What I've got here sucks :(
    And the log isn't all that great. Can the fping invocation be wrapped
    somehow to produce decent logs, e.g. via "tee"?
    
    BTW, I already tried IP addresses instead of hostnames. Nada.
