Spine correct values but unknown shows up in Cacti logs.

[kaf3773]

I am running Cacti 0.8.8c.

When I run Spine from the command prompt it shows it is getting correct values. see below

Code: Select all

[cacti@cactirtm01 cacti]$ ./spine -V 3 -R 4470 4470
SPINE: Using spine config file [spine.conf]

But in Cacti logs the unknown(U) shows up as output and therefore data does not show up in graph

Code: Select all

10/19/2017 08:55:36 PM - SPINE: Poller[0] Host[4470] TH[1] DS[9110] SCRIPT: perl /var/www/html/cacti/scripts/itp_lsn_util.pl 192.168.1.12 asd-itp5, output: U

Help will be very much appreciated.

Thanks

I eventually got a solution for this by doing this

Code: Select all

*/5 * * * * . /home/cacti/.bash_profile; /usr/bin/php /var/www/html/cacti/poller.php > /var/www/html/cacti/log/cacti.log 2>&1

Instead of the below

Code: Select all

*/5 * * * *  /usr/bin/php /var/www/html/cacti/poller.php > /var/www/html/cacti/log/cacti.log 2>&1

Hopefully this helps somebody.
