Custom script not returning data after upgrade to v1.02

[mrquad450]

I have a php script that goes off and collects data, printing it back out to the system. This exact script worked fine until I upgraded to v1.02 a little over a week ago - then it stopped displaying data for all but 2 of the items. Once v1.03 came out this week, I upgraded to it to see if helped - it actually broke the two that were working.

Here's the script:

The individual output fields are simple just the name - EXACTLY as it is written out by my script - and have the update RRDfile box checked.

I've tried the script manually - it works great - no issues. For some reason the polling doesn't appear to be liking it - though CLOG isn't showing any errors in requesting that data either.

I'm a bit at a loss after tweaking with it for a couple of weeks... Looking for some advice.

The script looks like it should function just fine (there are a few things that should be written just for codings sake) One thing is you should remove that closing PHP tag or the blank line after it. It is basically causing it to also output a newline.

The real question I have is why isn't the output you are showing have the proper space between the data sets? The echo is there in your script.

I think that was a relec of how I copied/pasted...

Here's the actual output:

That looks better...

Again, this worked perfectly prior to the upgrade, but hasn't worked since the upgrade...Not sure what has changed in this area of code?

Any suggestions for better method of troubleshooting this? It seems far simpler to troubleshoot SNMP based problems rather than script based... I'm open to suggestions...

I am wondering if the colons in the time are killing it (since colons are also a separator field). After this part,

Code: Select all

$value = $row->value;

try adding this

Code: Select all

if ($name == 'time') {
  $value = 1;
}

Here's the output from the updated script (adding the time=1 solution, and I added date=1 as well to be sure):

It is updating the rrd as I'd expect -- and I've actually got two of the values from above populating now... Air_Diff and Geo_Diff - none of the rest are working?

Hmmm... I think I've figured this out - but don't know how to fix it.

This was all set to 1 minute polling back in v0.8.8b - upon upgrade it shows 5 minute polling interval using the new 'Data Source Profiles' - however, I have no clue (nor can find any docs) how to create a new 1 minute polling.

Here's what rrdtool shows:

ds[Boiler_Input].index = 0
ds[Boiler_Input].type = "GAUGE"
ds[Boiler_Input].minimal_heartbeat = 120
ds[Boiler_Input].min = -1.0000000000e+02
ds[Boiler_Input].max = 2.0000000000e+02
ds[Boiler_Input].last_ds = "66.537498"
ds[Boiler_Input].value = NaN
ds[Boiler_Input].unknown_sec = 1

Here's the working version for AirDiff:

ds[air_differential].index = 1
ds[air_differential].type = "GAUGE"
ds[air_differential].minimal_heartbeat = 600
ds[air_differential].min = -1.0000000000e+02
ds[air_differential].max = 2.0000000000e+02
ds[air_differential].last_ds = "0.457069"
ds[air_differential].value = 4.5706900000e-01
ds[air_differential].unknown_sec = 0

So, again, I think this is a Data Source Profile issue - but how do I fix this? You can't (from what I can tell) update the minimal heartbeat with rrdtool tuner...?

I'd rather go back to 1 minute polling for the entire system...is that possible to change somewhere?
