Hi.

cactid fails to read variables from a script when a space character exist at the end. Would it be possible for cactid to format the output before processing it so it became more fault tolerant?

Below is perl,

$string =~ s/.$//;

I'm using lastest cactid (0.8.6c)

Your perl doesn't help me much. Could you provide an example of what type of output would fail. Use double quotes to show space.

Sure!

I am using a perl script to fetch WMI:MsDNS information from a Windows server. The output looks like this,

Sending a wmi-request from the poller box,
Code:

$/scripts/win32_wmi_msdns -h our-dns-server


The output (Qouted, as per your request)
Code:

"Total:1622858 Notify:0 Update:19881 TKeyNego:2448 Standard:1600529 A:1472562 NS:1067 SOA:18837 MX:7563 PTR:1229 SRV:98840 ALL:0 IXFR:0 AXFR:1 Other:430 "



cactid thinks
Code:

02/11/2005 01:26:27 PM - CACTID: Poller[0] Host[27] WARNING: Result from SCRIPT not valid. Partial Result: Total:1610661 Notify...
02/11/2005 01:26:27 PM - CACTID: Poller[0] Host[27] SCRIPT: /scripts/win32_wmi_msdns -h our-dns-server, output: U
02/11/2005 01:26:27 PM - CACTID: Poller[0] DEBUG: SQLCMD: insert into poller_output (local_data_id,rrd_name,time,output) values (351
,'','2005-02-11 13:25:02','U')
02/11/2005 01:26:27 PM - CACTID: Poller[0] Host[27] DEBUG: HOST COMPLETE: About to Exit Host Polling Thread Function



So i solved this issue by removing the last "space" at the end from the output.

Considered using the W32 DNS Statistics Perl Script using WMI script? That works just fine for me on Win2K3.

What script I use doesnt matter in this case. Please reread thread.

Blank space at end of script causes CACTID to ignore data.

Not in my case. Here cactid whinks that space at the end is just a delimiter, and waits for more data.

Sorry, please let me restate. If you have a blank at the end of your script output, Cactid will Vomit intentionally.

So you say it's a feature. I think it's a bug.

Feature. Although, I could trim the string to make it a little happier but not without a cost (CPU Cycles).

Yea well.

This would stop lots of stupid "Hey, my cactid wont poll blah, I just get U: ..., what's wrong" -questions

I think cacti/cactid is great anyway.

Christopher,

I do understand. The new check did catch a few people during thier upgrades, but the lions share have revised thier scripts. I am working on a new release to Cactid as we speak. I'll see what I can do.

Thanks,

Larry
