All,
I have read this page, which got me started :
http://blog.vuksan.com/2011/02/20/json-representation-for-graphs-in-gang
lia/
Now I have this problem:
In ganglia 3.4.2, I am trying to get the following to work:
- I created a webs_report.json file in graph.d.
- I named a custom metric that I am collecting via gmetric from the host
named in the json, like this:
{
"report_name" : "webs_report",
"report_type" : "standard",
"title" : "Web Server Response Time Report",
"vertical_label" : "Seconds",
"series" : [
{ "metric": "Ext-NewWeb01-Entry", "color": "3333bb", "label": "Web
1", "line_width": "2", "type": "line" },
{ "hostname": "SD1GGL01LX.SAKSDIRECT.COM" "clustername": "SaksGanglia"
},
]
}
I have the following file in the rrd directory, and it is being updated
from the host:
[root@sd1ggl01lx SD1GGL01LX.SAKSDIRECT.COM]# ls
boottime.rrd entropy_avail.rrd
mem_mapped.rrd tcp_closed.rrd
bytes_in.rrd Ext-NewWeb01-Entry.rrd
Yet my graph appears with no information in it, not even the vertical
label, and says "No matching metrics found"
Any ideas? Am I supposed to define that metric somewhere else besides
creating it with gmetric and sending it from the host?
