[hobbit] RE: Trying to create a graph

Tom, 


I am sending only 1 line of data, there is another example below where I send 3 lines of data and use two. The MSG var was a sloppy leftover from snagging an example script, probably slabinfo - disregard it.
 
When changing a graph stanza in hobbitgraph.cfg I normally kill the old rrd file.  There are ways to parse those rrd files to see what info is in there (look at rrdtool dump options).  Might be a good idea to see if you are even getting the data or if you are getting NAN.  NA2CPU : ${NA2CPU}  note the quoting

By the way, what do you have in:
/home/xymon/client/etc/clientlaunch.cfg?

I'm sure that others on the list who are more familiar with this can assist if you are not able to sort it out with my scattered bits of info.... 



Here is another example where data is sent and graphed:


From client/ext script which runs from client/etc/clientlaunch.cfg
# spew
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR `$DT`

`$MYSQLADMIN --port=$port -u$user -p$pass extended-status | $GREP -i $var | $AWK '{print "Bytesrecevied:",$4}'`
`$MYSQLADMIN --port=$port -u$user -p$pass extended-status | $GREP -i $var2 | $AWK '{print "Bytessent:",$4}'`
`$MYSQLADMIN --port=$port -u$user -p$pass extended-status | $GREP  $var3 | $AWK '{print "Connections:",$4}'`

"

Tim,
        That worked for the example under HELP --> Custom Graphs.  (slab
works just fine ...)
        But, I am still having a problem getting a graph for my data.

        Question:
                You have a MSG= set but you don't send it in the
'status' message?
                You do send the pair space separated though.

                I am sending about 8 lines of information from the MIBS
of the Juniper first.
                Then sending the PAIR of values.

                I originally was doing a 'status' and then a 'data' 'bb'
command and that did not work.

        After I have parsed the information, it looks like this when you
click the ICON (IP changed):

                Wed Jun 9 15:33:59 MDT 2010

        USERS :  335

-----------------------------
The 'USERS : 335' is the value to use as a pair.

Here is the snippet of code where I send it in from:
/home/xymon/client/ext/SNMP-Juniper.sh
L=log-file

          # Now we send the status message to Xymon
        # ---------------------------------------
        BB=/home/xymon/server/bin/bb
        BBDISP=127.0.0.1
        $BB $BBDISP "status $DEVICE.$COLUMN $COLOR `date`

        ${MSG2}

        USERS : $USERS
        "
        RC=$?
        if [ "$RC" -eq 0 ]; then
            echo -e "        Return Code from STATUS 'bb':  0"
>>$L
        else
            echo -e "        Return Code from STATUS 'bb':  $RC"
>>$L
        fi



Here is the entry in /home/xymon/server/etc/hobbitlaunch.cfg:
All other info about the other scripts has been removed.

        [hobbitclient]

And
        NCV_online="USERS:GAUGE"

IS 'online' the incorrect term?

Tom,

For this test the hobbitserver is the client, so
client/ext/somescript.sh is where the script is at.  Sorry I completely
missed that when looking at what you wrote!

So from client/etc/clientlaunch.cfg:
[NA2CPU]
        ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg
        CMD $HOBBITCLIENTHOME/ext/na2.sh
        LOGFILE $HOBBITCLIENTHOME/logs/na2.log
        INTERVAL 2m


Script outputs same data format as yours
...
NA2CPU="`$EGREP Busy $datafile | $AWK '{print $2}'`"

if [ $NA2CPU -gt 78 ]
   then
      COLOR=red
      MSG="na2 CPU load is high"

fi
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR `date`

NA2CPU : ${NA2CPU}
"
...

From the main server/etc/hobbitlauch.cfg you should already have:
[hobbitclient]
        ENVFILE $somepath/client/etc/hobbitclient.cfg
        NEEDS hobbitd
        CMD $somepath/client/bin/hobbitclient.sh
        LOGFILE $BBSERVERLOGS/hobbitclient.log
        INTERVAL 5m

Tim,
        Pardon me for asking, but I am trying to compare and isolate my
problem.

        What is the name and location of the script your are running?
Usually in server/ext directory.
        What is the name of the ICON to place the graph under?
        What does the 'bb' command that sends the data look like?
        And, what does the data pair(s) look like?  E.g.  "USERS:228" or
"USERS : 229", etc.

        What did you add to hobbitlaunch.cfg?

         Thanks,

Not sure if this will help or just mis-guide you so take with a grain of
salt.

Your config looks very similar to one of the graphs I recently added for
a NetApp box.  One thing that I did differently is in the use of the
names.  Here is an example:

hobbitserver.cfg:NCV_NA2CPU="NA2CPU:GAUGE"
NA2CPU=ncv is also defined in the other two vars in that file.

hobbitgraph.cfg
...
[NA2CPU]
        -W redacted

        YAXIS NA2 CPU

...

All assistance is greatly appreciated!


I have a simple number that I want to have graphed in Xymon.
Running 4.3.0-0.beta2 on CentOS 5.4.

I have a script that is populating the information from our Juniper
SSLVPN device(s).
I created a new ICON 'online' where there is a lot of information passed
for display by clicking the 'online' icon.
This is done using 'bb' with 'status'.

One of the values displayed is the number of web users.
I create a file of values for a history but I want to pass the value
from each run to the Xymon as 'data' to 'bb'.

The pair from each run is:      USERS:277    with the 277 changing with
every 5 minute run.

I placed the script in the /home/xymon/server/ext directory called:
SNMP-Juniper.sh

Per the Xymon Help --> custom graphs document:

I edited the following files:

                /home/xymon/server/etc/hobbitlaunch.cfg

                                # Tom Schmitt script in server/ext

     ENVFILE /home/xymon/server/etc/hobbitserver.cfg
                                                     CMD
/home/xymon/server/ext/SNMP-Juniper.sh
                                                     LOGFILE

                                                    INTERVAL 5m

                /home/xymon/server/etc/hobbitgraph.cfg
                I only want to see a single line showing the number of
USERS at the 5 minute timeframes.

                At the end of the TEST2RRD=".....,online=ncv"
                At the end of the GRAPHS=".....,online"
This was mentioned elsewhere so I tried it.
                Added the following line:
                                NCV_online="USERS:GAUGE"


I only see a small graph box with "X hobbitgraph ncv:online" in the box
under the icons:  online and trends
But no data graphed
If you click on it, you get the hourly, daily, weekly monthly graph as a
small box with no data either.
