Ben,
As you probably already know, the code is in header.php -
if( $context == "cluster" )
{
if (!count($metrics)) {
echo "<h4>Cannot find any metrics for selected cluster
\"$clustername\", exiting.</h4>\n";
echo "Check ganglia XML tree (telnet $ganglia_ip
$ganglia_port)\n";
exit;
}
$firsthost = key($metrics);
foreach ($metrics[$firsthost] as $m => $foo)
$context_metrics[] = $m;
foreach ($reports as $r => $foo)
$context_metrics[] = $r;
}
---------------------------------------------
So what to do?
Hack header.php about line 417 like this:
# $firsthost = key($metrics);
# foreach ($metrics[$firsthost] as $m => $foo)
# $context_metrics[] = $m;
foreach($rgmetrics as $m => $foo) {
$context_metrics[] = $m;
}
foreach ($reports as $r => $foo)
$context_metrics[] = $r;
}
---------------------------------------------
Fill the rgmetric array in ganglia.php:
$rgmetrics = array(); # Global decl.
In function start_cluster:
function start_cluster ($parser, $tagname, $attrs)
{
global $metrics, $cluster, $self, $grid, $hosts_up, $hosts_down;
global $rgmetrics; # decl.
and a little furth down in start_cluster function:
case "METRIC":
$metricname = $attrs[NAME];
$metrics[$hostname][$metricname] = $attrs;
$rgmetrics[$metricname] = $metricname;
break;
I would make a patch but my code is modded already.
This was also, errm, realtime programming - I did it just then.
Let me know if this is enough...
regards,
Richard

Subject: [Ganglia-general] Metric pull-down menu not showing all metrics
All,
I am curious how the Metric menu in the cluster view gets populated. I
have a number of my hosts reporting metrics that the others don't. For
example, the hosts that are running mysql and replicating from a
different database report how many seconds they are behind their master,
but only 10 out of my 30 hosts run mysql.
The mysql_slave ganglia metric does not usually show in the Metric
pull-down menu.
Previously, I had only one cluster, so clicking on 'Grid' just went
straight to the cluster. For some reason, after clicking on 'Grid', I
could see all the metrics that are reported. As soon as I chose a
metric, only some of the metrics were present in the Metric pull-down
menu. I think only the metrics present on the first host in the cluster
list are present in the pull-down menu.
Now I have more than one cluster in my grid, so clicking on Grid no
longer gives me all the metrics in the Metric menu. I am now unable to
see my mysql_slave metric without manually typing it into the URL
string.
Suggestions?
