I could use this for a great number of data sets! -----Original Message----- From: Henrik Stoerner [mailto:henrik at hswn.dk] Sent: Friday, February 04, 2005 5:51 PM To: hobbit at hswn.dk Subject: [hobbit] Custom graphs (was: temperature-larrd.pl) Importance: Low On Fri, Jan 28, 2005 at 04:47:27AM -0700, Charles Jones wrote: > Speaking of this, it sure would be nice to have some sort of plugin > system, or something for easily creating custom graphs.

I've found a way of doing this that keeps as much as possible of the RRD handling in Hobbit, and makes it easy to use custom scripts (written in your favourite scripting language) to process a message and pick out the interesting data you want to put into a graph. Basically, you tell hobbitd_larrd which status- or data-messages are handled by an external script, and what the script is. Your script is then called when such a message arrives, and is fed the status message in a file. In return, the script must output the RRD definitions for the data you want to store, a filename for the RRD file, and the values. E.g. if you have a message like green Weather in Copenhagen is FAIR Temperature: 6 Wind: 4 Humidity: 72 and you want to track these, then this script would do: #!/bin/sh # Input parameters: Hostname, testname (column), and messagefile HOSTNAME="$1" TESTNAME="$2" FNAME="$3" # Analyze the message we got TEMP=`cat $FNAME | grep "^Temperature:" | awk '{print $2}' WIND=`cat $FNAME | grep "^Wind:" | awk '{print $2}' HMTY=`cat $FNAME | grep "^Humidity:" | awk '{print $2}' # The RRD dataset definition echo "DS:temperature:GAUGE:600:-30:50" echo "DS:wind:GAUGE:600:0:U" echo "DS:humidity:GAUGE:600:0:100" # The filename echo "weather.rrd" # The data echo "$TEMP:$WIND:$HMTY" exit 0 Does that seem like a usable plug-in facility ?

[hobbit] Snapshot reports

You are correct....the two seem to follow each other. Sorry for the false alert. I need to let it run longer.

So how far back does your history record go if you view the history in the normal Hobbit display ? Henrik To unsubscribe from the hobbit list, send an e-mail to hobbit-unsubscribe at hswn.dk

custom memory1 larrd graph def
by tgeorgoulias＠nandomedia.com 04 Feb '05

04 Feb '05

In case anyone is interested, I created a new larrd def for hobbitgraph.cfg that uses the name "cached" instead of "real" in the trend chart. I did it because I found "real" and "actual" to be too confusing, since the words mean roughly the same thing in day to day use, but not on a Linux system! :) Just thought I'd throw it out there in case someone else wants to use it.

Snapshot reports

After further testing, it appears that the snapshot only goes back about 1.5 hours. Anything after that shows clear icons/status and I have had this new version (RC1) running for about 24 hours. Anybody else see this? KEvin

reports

I have some questions about snapshot reports. No matter what time I pick for a report, with the exception of the default time (right now), I get clear icons. What does this mean? Shouldn't this report show a "snapshot in time" of the network/hosts?...Or am I thinking of this all wrong? Please advise. Thanks KEvin

[hobbit] Hobbit 4.0-RC1 available
by rwaegner＠questia.com 03 Feb '05

03 Feb '05

Oh yes indeed! Excellent! I even have my BEA column now! One quick question though, the bea column consists of only a bea heap utilization graph. Is there a number of other bea stats available? like the apache multiple graphs "LARRD:*,apache:apache1|apache2|apache3"? I have the two enterprise OID strings in Henrik's bea-snmpstats.sh ext file, but only one graph (heap) is displayed, and it's empty! I've done snmpwalks to the servers (to both OIDs) and get VAST amounts of data.. Rick
