nagiosgraph / Discussion / Feature Requests: nagiosgraph.conf and heartbeats

emilio65 - 2012-02-16

Hi expert
In nagios I check the disk space availability each 30 minutes (1800 secs)
In order to get a graph of the % used space I put in nagiosgraph.conf this line

heartbeats = .*,Check_Disco_D_RRD,.*=1850

Check_Disco_D_RRD is the service name.

This line seems doesn't work and I get and empty graph

Some one could tell me where is my error ?
Thanks and Regards
Emilio

if you sample every 30 minutes, you should specify these:

stepsizes=.*,Check_Disco_D_RRD,.*=1800 heartbeats=.*,Check_Disco_D_RRD,.*=3600

the stepsize should be equal to the nagios sampling interval, and the heartbeat should be twice the stepsize.

however, there is a bigger problem - a bug in nagiosgraph 1.4.4. see the FAQ 'What settings control the amount and frequency of data stored?' for the fix. it has been fixed in 1.4.5.

i hope to release 1.4.5 in the next week or two. the release is nearly complete, but i still need to do testing on various platforms and configurations.

this info set in nagiosgraph.conf don't work

stepsizes=.*,Check_Disco_D_RRD,.*=1800
heartbeats=.*,Check_Disco_D_RRD,.*=3600

Justo to confirm this I set the debug option in the nagiosgrap.con file:

debug_insert = 5
# if this is set to a hostname, then only log for this host
debug_insert_host = SVZVRDBVVC001W8
# if this is set to a service, then only log for this service
debug_insert_service = Check_Disco_D_RRD

and the I delete the rrd file
Check_Disco_D_RRD___DISCO.rrd

Here what I found in the nagios log file

The step is 300 and the hearbeat is 1000 (both default value)

I can see the same info with the command
rrdtool info /var/nagiosgraph/rrd/SVZVRDBVVC001W8/Check_Disco_D_RRD___DISCO.rrd'

Many thanks for all your help

there is a bug in 1.4.4 that causes nagiosgraph to ignore 'stepsizes' and 'heartbeats'. in the function 'readconfig' in ngshared.pm (line 805) change:

chomp $key

to:

chop $key

btw, what nagios plugin are you using to check for number of users?

the log shows odd entries about 'no service found' for a nagios plugin with output of:

ed users||connect_users=40;100;200

OK , I modified the chomp to chop and now I the RRD file seems well configured
(rrdtool info command show the step=1800 and heatbeat=3600)

About the connected user :
Are the user connected to MS SQL.
I use the nagios : check check_mssql_health and in the status information I see
OK - 34 connected users

The Performance Data are connect_users=34;500;550
500 is warning limit and 550 is critical limit
At the moment (also as you see , there is the error in the log) I'm able to
get the right RRD file with the 3 datas (number user, warning and critical)

Hi,

I use nagiosgraph 1.4.4.

As reported in the official doc "A typo in 1.4.3 and 1.4.4 prevents the specification of stepsizes, heartbeats, and resolutions. It has been fixed in 1.4.5."

I do not find the versione 1.4.5 (it is available?), but I tried this info:

there is a bug in 1.4.4 that causes nagiosgraph to ignore 'stepsizes' and 'heartbeats'.
in the function 'readconfig' in ngshared.pm (line 805) change:
chomp $key
to:
chop $key

Within my Nagios there are some services checked every 30 secs. This is the current link of the graph (useful to read the hostname, the service and the database).
.../nagiosgraph/cgi-bin/show.cgi?host=X14-mtc&service=Beacon_Power_Level&db=mtc_beacon

I'd like to graph the values every 30secs so I changed the following variables

heartbeats = X14-mtc,Beacon_Power_Level,.=60
stepsizes = X14-mtc,Beacon_Power_Level,.=30

I deleted the existing RRD file, but it has been created with the default values

...
rrd_version = "0003"
step = 300
last_update = 1384940553
header_size = 1208
...

Can anyone help me?
Thanks

I haven't had the chance to release 1.4.5, so you will have to check it out via subversion or git: git clone git://git.code.sf.net/p/nagiosgraph/git nagiosgraph-git
