Re: [hobbit] Representing disk data for graphing



OK, I understand now.  Thanks for all of the information.

With that I do not understand why I'm getting a graph with the datapoint with one of the items on my status message:

status vm1.disk green Wed Oct 11 22:12:19 CDT 2006 [vm1] Disk/SFS Utilization OK

(this is all on one line)

At this point '11' is a datapoint on the graphs and has a value of zero/

No, the problem is not the root filesystem, the problem is that
do_disk.c recognize a disk line if that line contains a "/" inside the
line and will skip that line if it start with "&" and it will skip the
line if it contains the string "red" or "yellow".
This is mostly done for Unix filesystem report that looks something
like:

yellow  Wed Oct 11 21:55:16 CEST 2006 - Filesystems NOT ok

&yellow /sapdata/QQ8 (94% used) has reached the WARNING level (90%)

Filesystem            kbytes    used   avail capacity  Mounted on

In this case it need to skip line starting with "&red" or "&yellow"
because they are only the alert at the start of the message so that
users know with a direct look what's wrong. Those line have to be
skipped.
So a line containing a "/" and not containing a "&" at the start or the
word yellow and red will not be skipped.


I think that you've to change the way you send data because probably the
line with data you send will be skipped if they're reported to hobbit
with "&red" or "&yellow" too.

You can use something like the test I pasted above to send data that
should be recognized as unix filesystem.

Oh, I see, it's looking for a root filesystem line? This architecture doesn't implement a root filesystem. In any case I would want to just pass over it, reporting and graphing the root is as important as any of the other (IMHO).

Not really a problem I think but some misinterpretation by the do_disk.c that is happening if the first line have a "/"
your first line is:
"color" 11 Oct 2006 07:45:23 Disk/SFS Utilization OK


I added "color" because it's passed also if you don't see it on the first line because it's the page color.
The line checking the various line of disk report to get
data line are:

/* AS/400 reports must contain the word DASD */
if ((dsystype == DT_AS400) &&
(strstr(curline, "DASD")
== NULL)) goto nextline;

/* All clients except AS/400 report the mount-point with slashes - ALSO Win32 clients. */
if ((dsystype != DT_AS400) &&
(strchr(curline, '/') ==
NULL)) goto nextline;

                /* red/yellow filesystems show up twice */
-->                if ((dsystype != DT_NETAPP) && (dsystype !=
DT_NETWARE) && (dsystype != DT_AS400)) {
-->                        if (*curline == '&') goto nextline;
-->                        if ((strstr(curline, " red ") ||
strstr(curline, " yellow "))) goto nextline;
                }

for (columncount=0; (columncount<20);
columncount++)
columns[columncount] = "";
fsline = xstrdup(curline); columncount = 0; p = strtok(fsline, " ");
while (p && (columncount < 20)) { columns[columncount++] = p; p = strtok(NULL, " "); }


So your dstype is not DT_NETAPP or DT_NETWARE or DT_AS400,
the first
line have a "/", if the color is not "red" or "yellow" that
line will
be treated as a data line and it will get some data from it and construct a rrd file.

I had the same problem with netapp filers disk reporting of
my script
when sending data with the /group option because the /group will be sent to the rrd disk module (you'll not see it in the page but it's there like the color) and in that case I started to have rrd file named with HH:MM:SS ... I got the problem when i started to
get 50-60
of those files in each filers rrd file.

So it should be safe to skip the first line of the data reported by the do_disk because it will not contain filesystems data
(don't know
if it can create problem with netware or as400 but it works with netapp/unix/windows clients at least).

Thanks for the patch. Is there something in the first line itself that might be causing the problem?

Hi,
One of the problem  is that the first line is got from the
do_disk.c
and it have a "/" so it's checked as a data source.
I posted a patch some days ago to solve this problem that
also happen
if you use the /group with the bb command. I don't know
if this alo
This will skip the first line of the do_disk message and
it should
then work as expected (at least it work with /group)

Oops, I spoke too soon. It did not work with the icons as
I thought.
I'm back to no icons and four data points per graph (which looks
good) and the mysterious third token on the first line
data point.

Indeed. I got a suggestion to add the &clear icon to the
heading and
now it works. Unfortunately I now get one very crowded graph, otherwise good progress.

Thanks for your help!

Yes, the "&color" now counts as a token, so any
grep/awk/sed (or
equivalent) is going to be off by one. Is this
information included
in the overall data blast from the Hobbit client? If so,
you might
consider tacking the colors at the END of each line and
see if the
Hobbit parser starts working again.

For reference, here is something from a Solaris system:

Wed Oct 11 12:19:50 CDT 2006 - Filesystems OK

Notice that the filesystem is token 1, the usage is
token 2, and
available space is token 3, etc., etc.

These are just ideas. I've written 7 or 8 custom tests
of my own
with my own RRD parsing at the end, so I quickly became
acquainted
with the need for agreement between the "pitcher" and the
"catcher".
