Subject: Compute Service
Message-ID: <4F295923.4060509@jeremykister.com>

must expr have a %{ Top:object } to math ?

Or, there a reason that something like:

Service Compute {
	debug:	yes
	expr:	500 + 1
}

will make the compute service continuously fail with:
  Service start
  start compute
  service not ready: Top:Foo:Cluster1:SSG:licenses
  Service done


?



I realize the compute of a static expr may seem odd, but it is very 
convenient to get a variable into Argus as an object.

e.g.,
 > cat 122_more
  Group "More122" {
   Service Compute {
    expr: %{Top:Test123:foo} + %{Top:More122:bar}
   }
   Service Ping {
     uname: bar
   }
  }
 > cat 123_test
#!/usr/local/bin/perl

my %data = (one => 1,
             two => 2,
            );

cat <<__EOA__
  Group "Test123" {
   Service Compute {
    expr: $data{one} + $data{two}
    uname: foo
   }
  }
__EOA__

yes.

'compute' was intended to be used for computing something
based on the results of other monitored services.

I see no way these messages could come from that config.
they came from something with a '% 
{Top:Foo:Cluster1:SSG:licenses}' (and something else) in the expr.

yes, that seems odd.

you want argus to calculate 1 + 2? why? so argus can page you if Q  
changes the laws of mathematics?

your example is generating an argus config using perl.
perl can add numbers together itself:

	my $x = 500 + 1;
	print "$x\n";

.. In God we trust, everything else we monitor.

how would i use 'print "$x\n" in the 123_test file so that a Compute 
object in the 122_more file could use it ?

see, my 123_test file has a pretty hash at the top where there's lots of 
data.  i don't want to denormalize my data by having to put these values 
all over the place.

so i was trying to use Compute so that I could expose the data in my 
123_test file to all of Argus so that other objects could see it.

Subject: Graphing Fails
Message-ID: <20120223122840.16d01ade@ita-martin>

Hi,

some month ago we switched on graphing. Now more and more graphs fail
to graph. We get a pink image displaying the text: 

  ARGUS CGI: GRAPH ERROR. cannot generate graph. picasso failed. see
  web server error log.

I the stderr of the arguscgi.pl script I get 

  data point out of order at /usr/local/lib/argus/picasso line 131
  picasso failed. cannot generate graph image.

This only seems to affect the 'Samples' Graph. We have on many (but
not all) data sources.

Running on FreeBSD 7.4 / amd64 / Perl v5.8.9 / lighttpd 1.4.28 / mod_cgi


Any ideas how to fix this?!

Thanks,

Martin

Message-ID: <4F4BDA19.1070001@gaslightmedia.com>

is Schedule checking inherited?  i have a group of units that have a 
high posability of going down at a certain time each day due to a cron 
that we have running on a router that causes things to be unavailable.  
I was hopping that i could just put this in that group and it would 
cover them all but not sure.
