Thanks for the reply. Unfortunately, I've already been through that documentation over and over.

But I think I stumbled onto the answer by just blindly guessing and changing things around.

I changed my custom script to send in "green" status messages rather than "clear", and what do you know, an RRD datafile was created.

My custom script was sending in data with an indication of "clear". This is what I normally use for tests I'm working on that are sending data, but I haven't applied any red/yellow condition checking yet. i.e., This is my way of saying "Here's some raw data to view on a web page, but without any interpretation applied to it yet". I can't remember what the original intent of "clear" was, I stole that color for my own use years ago when I started with Big Brother. I imagine Hobbit was applying the original meaning of "clear", whatever it was, and therefore not moving the data to an RRD file. Maybe this hobbit operation is by design, and that's fine with me, ... it would be nice if the documentation on how to create custom graphs mentioned it however.

Thanks!

I'm still not getting any RRD data being populated after the following changes:

(1) Added "recent" to the GRAPHS line in hobbitserver.cfg. I thought this line was only for putting things in the trends column, but I added 'recent' to it anyway.

(2) Changed my NCV_recent line in hobbitserver.cfg to "*:GAUGE" rather

than individually listing each dataset.

(3) Restarted hobbit.

(4) Changed my status messages to not have any spaces in them They were like this e.g., "five<space>:<space>27 Now they are like this e.g., "five:27"

Still no RRD database file being generated. I'm looking in the ....../data/rrd directory for some file named like *recent*.rrd

The messages I'm sending from my custom script are status messages, and they show up on the regular webpage displays, updated every five minutes. It looks like the rrd process is running too:

hobbit at stars-dev <mailto:hobbit at stars-dev>-> ps -ef | grep status hobbit 593 587 0 21:52 ? 00:00:00 hobbitd_channel --channel=status --log=/development/hobbit/logs/rrd-status.log hobbitd_rrd --rrddir=/development/hobbit/data/rrd

I looked through the ...../logs/rrd-status.log and rrd-data.log files and there is no mention of 'recent' in there.

Any ideas on where I should look next to debug this? Thanks in advance for any help or guidance.

I'm trying to do my first custom graph, using data collected from a custom script.

The script collects data fine, and successfully updates hobbit at it's

regular five minute increments. The data as sent looks like this:

five : 17 ten : 24 fifteen : 30 twenty : 42 thirty : 62 fortyfive : 81 sixty : 108 ninety : 166 onetwenty : 218 oneeighty : 349

The column name is 'recent'. Here's BBHOSTS:

group-only recent|pending|stuck Maestro 0.0.0.0 maestro_alarm_cases # prefer noconn recent pending stuck NAME:"Alarm Cases"

and hobbitserver.cfg:

TEST2RRD="cpu=la,disk,inode,qtree,memory,<more stuff>,ports,clock,lines,recent=ncv"

NCV_recent="five:GAUGE,ten:GAUGE,fifteen:GAUGE,twenty:GAUGE,thirty:GAUGE ,fortyfive:GAUGE,sixty:GAUGE,ninety:GAUGE,onetwenty:GAUGE,oneeighty:GAUG E"

I stopped/started hobbit server. I've been watching the 'recent'

column update regularly every five minutes, for at least 45 minutes now.

But there doesn't appear to be any RRD data file for this 'recent'

test:

find /development/hobbit/data/rrd -name "*recent*" -print

The above 'find' command finds nothing related to 'recent' (although there are plenty of OTHER test's RRD files in that directory - default

tests - just not my custom test)

I must have missed something simple. I've gone over the hobbit webserver's HTML help on "Custom Graphs" several times, but can't find the cause of my error.

Double-check your settings using the documentation from your Hobbit installation at http|https://$BBSERVERWWWNAME/$BBSERVERWWWURL/help/howtograph.html

David,

Not sure if this helps you, but I change my graphs to reflect 24h, 7d, 30d, and 365d using this info below:

I don't know if that could be done in a config file, but it certainly can be done by altering the source. Take a look at hobbitd/hobbitgraph.c. Near the top there's a bunch of defines that tell rrdtool how to select the data: #define HOUR_GRAPH "e-48h" #define DAY_GRAPH "e-12d" #define WEEK_GRAPH "e-48d" #define MONTH_GRAPH "e-576d" "e-48h" means "end-of-data minus 48 hours", which is the start of the range, the end of the range being the end of the data. Change those numbers to whatever suits you best - i.e. e-24h, e-7d, e-30d & e-365d. You'll also want to look further down for blocks like this: if (strcmp(val, "hourly") == 0) { period = HOUR_GRAPH; persecs = 48*60*60; gtype = strdup(val); glegend = "Last 48 Hours"; } and fix those up. I guess that would be: persecs = 24*60*60; and glegend = "Last 24 Hours"; for the 24 hour graph. Similarly for DAY_GRAPH, WEEK_GRAPH & MONTH_GRAPH. Go back up to the main source directory and re-run make, then copy hobbitd/hobbitgraph.cgi over to hobbit's server/bin directory. Seems to work fine for me - I might even keep it like this... :) Ralph Mitchell

David

I need to look at my custom graphs with a higher resolution (shorter timeframe) than the default "Last 48 hours".

I tried the changes below in hobbitgraph.cfg (appended ":start=end-4h" to the DEF entries), but this didn't make any difference. I was attempting to get a "Last 4 hours" display.

... [recent] TITLE Incoming Cases YAXIS Count DEF:five=recent.rrd:five:AVERAGE:start=end-4h DEF:ten=recent.rrd:ten:AVERAGE:start=end-4h DEF:fifteen=recent.rrd:fifteen:AVERAGE:start=end-4h DEF:twenty=recent.rrd:twenty:AVERAGE:start=end-4h ...

I also tried "end=start+4h", not expecting that to give me what I wanted, but as a test to see if I could get a four hour window displayed. This directive appeared to be ignored as well. The display always shows "Last 48 hours".

If none of your servers are using them, look into the group compress option in bb-hosts.

I'll not be using the files, ports, or procs client-side tests, which show up by default with grey icons (different icons for fetchdata clients than for regular ones, too).

Can anyone tell me a way to disappear those columns from the display and save me a trace-trip through hobbitcgi.cfg and beyond?

See the hobbitd_client manpage for the "--no-clear-X" options.

Also, NOCOLUMNS in bb-hosts can be used (see the bb-hosts manpage).

Thanks. I can handle the C modifications. Looks like the default graphing options are hardcoded, and apply to all graphs. The defaults seem a bit odd ... I like your 24h, 7d, 30d, 365d ones better. I assume the 576d original max default value goes hand-in-hand with some hardcoded default used to set up the RRD data file.

While it might be nice to change the graphs with config settings rather than code changes, it sure is convenient the way Hobbit does all the setup for you without you really having to learn much about rrdtools. If I had to pick flexibility or convenience in this matter, I'd vote for keeping Hobbit's convenience the way it is.

Don't know if I'll actually go and modify the C code. It would be very easy to do, but it complicates future Hobbit upgrades, especially if support of what I do is inherited by someone else later, and that person doesn't happen to be a coder.

Thanks!

They happen to match how the data is stored in the RRD files, something Hobbit has inherited from the LARRD add-on for Big Brother.

576 data points in the RRA, 576 pixels in the graph -- maintains a one-to-one ratio to avoid "blocking" in the graph. 576 because that was to biggest the graph could be and have it fit "comfortably" on an 800x600 display (back in 2001).
