Trouble starting ext test to rrd, graph
I wrote a script that will pull out a few lines of unbound stats and that submission appears good. I've got a green column by the host on the Xymon server. The web page is showing this:
totalnumqueries:51 totalnumqueries_ip_ratelimited:0 totalnumcachehits:22 totalnumcachemiss:29 totalrecursiontimeavg:0075215 numquerytcp:0 numquerytcpout:0 numanswerrcodeSERVFAIL:0 unwantedqueries:0 unwantedreplies:0
The part where I'm stuck at is that it won't generate RRD files. From the help page it suggests Ijust add a value to TEST2RRD and NCV_ like I've done here:
TEST2RRD="<allTheDefaultsHere>,unboundstats=ncv"
NCV_unboundstats="totalnumqueries:GAUGE,totalnumqueries_ip_ratelimited:GAUGE,totalnumcachehits:GAUGE,totalnumcachemiss:GAUGE,totalrecursiontimeavg:GAUGE,numquerytcp:GAUGE,numquerytcpout:GAUGE,numanswerrcode.SERVFAIL:GAUGE,unwantedqueries:GAUGE,unwantedreplies:GAUGE"
Something odd I did notice was that the link to the graphs (which have no images, no rrd, etc) will say "No DS called 'inodecache' in 'unboundstats.rrd'". What is the reference to inodecache?
I have restarted it with xymonlaunch on the server.
Now the data/rrd/ directory doesn't contain a host dir, I'm pretty sure that is something that will be created by Xymon.
Any idea what I'm doing wrong?

I create a new file in xymonserver.cfg.d so I can isolate all my configs. Here?s one of mine that works:
TEST2RRD="$TEST2RRD,E1Evt=ncv"
GRAPHS="$GRAPHS,E1Evt"
SPLITNCV_E1Evt="*:GAUGE"
SPLITNCV puts them in different files so if you add or remove stats later you don?t lose all your history, and you can use wildcards for the type. Other than that I don?t have any suggestions.

Hi Josh,
Something odd I did notice was that the link to the graphs (which have no images, no rrd, etc) will say "No DS called 'inodecache' in 'unboundstats.rrd'". What is the reference to inodecache?
I guess you took the graph definition from this guide (https://xymon.sourceforge.io/xymon/help/howtograph.html)?
[slab]
TITLE Slab info
YAXIS Bytes
DEF:inode=slab.rrd:inodecache:AVERAGE
DEF:dentry=slab.rrd:dentrycache:AVERAGE
LINE2:inode#00CCCC:Inode cache
LINE2:dentry#FF0000:Dentry cache
COMMENT:\n
GPRINT:inode:LAST:Inode cache \: %5.1lf%s (cur)
GPRINT:inode:MAX: \: %5.1lf%s (max)
GPRINT:inode:MIN: \: %5.1lf%s (min)
GPRINT:inode:AVERAGE: \: %5.1lf%s (avg)\n
GPRINT:dentry:LAST:Dentry cache\: %5.1lf%s (cur)
GPRINT:dentry:MAX: \: %5.1lf%s (max)
GPRINT:dentry:MIN: \: %5.1lf%s (min)
GPRINT:dentry:AVERAGE: \: %5.1lf%s (avg)\nOn the lines starting with ?DEF? you can see references to the data sources (DS) ?inodecache? and ?dentrycache?, these will have different names in your case, e.g. ?totalnumqueries?.
You can use the ?rrdtool dump? command to show the data sources contained in your rrd file, if I remember correctly some of your data sources will be truncated by Xymon, e.g. totalnumqueries_ip_ratelimited might be too long.
If you now what your DSs are called, you?ll have to edit the graph definition to reference the actual names, e.g.:
[unboundstats]
TITLE Unbound Stats
YAXIS Num
DEF:numqueries=unboundstats.rrd:totalnumqueries:AVERAGE
DEF:numcachehits=unboundstats.rrd:totalnumcachehits:AVERAGE
LINE2:numqueries#00CCCC:Total Queries
LINE2:numcachehits#FF0000:Total Cache Hits
COMMENT:\n
GPRINT:numqueries:LAST:Inode cache \: %5.1lf%s (cur)
GPRINT:numqueries:MAX: \: %5.1lf%s (max)
GPRINT:numqueries:MIN: \: %5.1lf%s (min)
GPRINT:numqueries:AVERAGE: \: %5.1lf%s (avg)\n
GPRINT:numcachehits:LAST:Dentry cache\: %5.1lf%s (cur)
GPRINT:numcachehits:MAX: \: %5.1lf%s (max)
GPRINT:numcachehits:MIN: \: %5.1lf%s (min)
GPRINT:numcachehits:AVERAGE: \: %5.1lf%s (avg)\nYou?ll need to define one DEF-line for each value you want to display on the graph (DEF:<Alias for further processing>=<rrd file name>:<data source name>:<consolidation function>).
Best regards,
Fabian

A couple of things:
RRD has a DS name length limit of 19 characters, so some of your longer names (numanswerrcodeSERVFAIL) are going to be truncated or possibly even cause the whole lot to be rejected. Also, there's a restriction on characters that can be used: [a-zA-Z0-9_]
In your webpage output you use numanswerrcodeSERVFAIL but in your NCV_ setting you have numanswerrcode.SERVFAIL (with a dot before SERVFAIL). I suspect these have to be identical to work. Also, you can't use dots in DS names as per the last point.
Cheers Jeremy

Thanks a ton for the help! It looks like between xymon config and RRD they're simply truncated and stripped of non alphanumeric characters. (example: totalnumqueries_ip_ratelimited) This is in the RRD (:
rrdtool info unboundstats.rrd
<snip> ds[totalnumqueries].last_ds = "109" ds[totalnumqueries].value = 8.4000000000e+00 ds[totalnumqueries].unknown_sec = 0 ds[*totalnumqueriesipra*].index = 1 ds[totalnumqueriesipra].type = "DERIVE" ds[totalnumqueriesipra].minimal_heartbeat = 600 <snip>
My RRD are actually in /var/lib/xymon/rrd *NOT* /var/lib/xymon/data/rrd so they were actually being made. I was looking in the wrong place (guide doesn't match my RPM).
Per the suggestion, I decided to split them using SPLITNCV. Honestly I don't see why you wouldn't just do this from the get go, it's so much easier and better.
