View traffic & error stats

I have working traffic link which I want to monitor for errors. But I am getting some error messages in the log;

02/06/2010 02:17:00 PM - WEATHERMAP: Poller[0] WARNING: [Map 85] MAPNAME: ReadData: LINK NODE1-NODE2_err, target: /var/www/cacti/rra/node2_errors_in_38776.rrd:errors_in:- on config line 744 had no valid data, according to WeatherMapDataSource_rrd
02/06/2010 02:17:00 PM - WEATHERMAP: Poller[0] WARNING: [Map 85] MAPNAME: ReadData: LINK NODE1-NODE2_err, target: /var/www/cacti/rra/node1_errors_in_38766.rrd:-:errors_in on config line 744 had no valid data, according to WeatherMapDataSource_rrd

The entry in the config file is:

LINK NODE1-NODE2_err
NODES NODE1 NODE2
BWLABEL none
WIDTH 4
OUTLINECOLOR none
USESCALE errors
TARGET /var/www/cacti/rra/node1_errors_in_38766.rrd:-:errors_in /var/www/cacti/rra/node2_errors_in_38776.rrd:errors_in:-

Does this look correct? Any ideas about the log entries?

That looks OK. Run with DEBUG logging for one poller cycle, and then look in the log for lines with ReadData in them - you'll see what rrdtool is returning, and what the plugin thinks about it.

Here is what was returned (I removed entries containing "add_note@Weathermap.class.php").

Things look OK, so I am not sure why it is giving warnings. Unless it is because everything is 0 (the link was error-free when the poll was run) ?

Any insight, Howie?

which version of weathermap is this? Because between 0.96a and 0.97:

# DS plugins that return one value and a null should work properly

Keep an eye out for 0.97a if this isn't urgent - there are another 10 bugfixes stacked up in that one.

2par · Post by **2par** » Wed Feb 10, 2010 2:18 pm

Yes, using 0.96a.

Will eagerly await 0.97a then.

Thanks for the help and the fast replies.

2par · Post by **2par** » Mon Feb 15, 2010 12:15 pm

I could not wait for 0.97a after all.

I installed 0.97, but now both of my links are showing as red and looking at the log i get values on both links, altho the link is error free (I double checked).

Still an issue with NULL ? Is this something that will work with 0.97a or is there something wrong at my end?

What is the BANDWIDTH set to on the error link? 4x10^-6 is quite a small number.

Anyway, it appears you have a scale where any value between 0 and 100% goes red. The value is between 0 and 100%.

Seems to be working fine to me.

My error scale looks like:

SCALE errors 0 0 none
SCALE errors 0 100 255 0 0

which I "stole" from this thread.

I assumed it was to be blank when the value was 0 and red when the value was something else (above 0).

BANDWIDTH is set to 10G which is default for new links. I didnt think the BANDWIDTH variable was important in this type of graph?

What are the 408 and 7888 values that are returned? The link is (at the moment) error-free, so I would expect it to come back with 0 and 0.

What is the BANDWIDTH set to on the error link? 4x10^-6 is quite a small number.

Anyway, it appears you have a scale where any value between 0 and 100% goes red. The value is between 0 and 100%.

Seems to be working fine to me.
My error scale looks like:

SCALE errors 0 0 none
SCALE errors 0 100 255 0 0

which I "stole" from this thread.
I assumed it was to be blank when the value was 0 and red when the value was something else (above 0).

BANDWIDTH is set to 10G which is default for new links. I didnt think the BANDWIDTH variable was important in this type of graph?

What are the 408 and 7888 values that are returned? The link is (at the moment) error-free, so I would expect it to come back with 0 and 0.

408 and 7888 are the results of adding up the targets. Which is why the resulting percentage is non-zero, which is why it's red.

So I guess the next step is to take a look at what data Cacti is actually collecting.

I went back to my debug log and checked the "rrd info" on the rrd files.
I came up with this:

I fear I am out of my depth here. All I can see is that it is reading the ds[errors_in].last_ds entry and using it. The other numbers I am unsure about, but I am confused why it is not using the ds[errors_in].value entry.

If this is basic cacti information, I'd be grateful if anyone can point me in the right direction. I did various seraching on the forum, but failed to find anything of relevance to this matter.

It would be useful to try removing the 'rrd_use_poller_output' line from the config, and see if it makes any difference (assuming you aren't using Boost). That way, Weathermap will be reading the rrd file (at the moment it is reading data direct from the poller, using completely different code).

After commenting out "rrd_use_poller_output" things look better.

All nodes return:

WEATHERMAP: Poller[0] DEBUG: [wmrrd_read_from_real_rrdtool@WeatherMapDataSource_rrd.php:421] [Map 85] MAPNAME: 0.0000000000e+00 is OK value for errors_in

WEATHERMAP: Poller[0] DEBUG: [ReadData@Weathermap.class.php:942] [Map 85] MAPNAME: Aggregate so far: 0 0

It concludes with:

WEATHERMAP: Poller[0] DEBUG: [ReadData@Weathermap.class.php:1023] [Map 85] MAPNAME: ReadData: Setting 0,0

The error links no longer show as red (since value is 0). Now I need to find a link with errors to test it futher.
