Hi All,
I've tried to use "rate" function to combine but it didn't work as
expected. How to combine the data below.
example; it returns empty query result
rate(ping_rtt_min{Description="1673(1)-Trunk28#PTV1801-3-LDX-RX1/TX1*#SG520_W#@1890606165@||DWDM-1-1||_NNI_ANK"}[10m])
*# HELP ping_rtt_min RTT Min
*
*# TYPE ping_rtt_min counter*

From that entry it looks like data values are being included within the
metric as labels. These need splitting out into their own separate
metrics (e.g. NNI_RTT_Min and Packet_Loss). As it stands you are
creating new time series for basically every scrape, which results in
the lines you are seeing in your graph. Also as it is a cardinality
issue it will cause problems with the data storage side of things too.
It is important that labels are never used for data values, and just
contain fixed descriptive entries (such as names, etc.).
If you correct that things should look better.
