POLLER: Poller[0] ERROR: The path: is invalid.

[Kar_man]

Hello,

I upgraded from 0.8.6j to 0.8.7, on my linux running cacti.

If I use spine then I get the error msg

"POLLER: Poller[0] ERROR: The path: is invalid. Can not continue"

If i change to cmd.php then it works.

When configured to use spine, if I run

/usr/local/php/bin/php poller.php

then spine works fine and is able to update the rra files. Not sure why this does not work and gives me the error when it does it by itself using spine as the poller !

Any help would be great. (spine version 0.8.7)
thanks

Did you check:

Console --> Settings --> Paths
Make sure the paths are correct, the paths require full path AND the binary itself e.g (/var/www/cacti/spine/bin/spine).

[Kar_man]

yes I did and the path is correct and points to the binary. Also when i run <path php> poller.php it works fine with spine as the poller.

The error message is supposed to show the spine path that is incorrect but i am getting a blank instead. Is this supposed to be configured in some other file as well ??? the database has the right path for path_spine as is seen in the settings table

thanks!

Is spine suppose to be executed from cactiuser? e.g.

Code: Select all

chmod a+x spine

Hi Randolf,

Yes I gave spine full permission.

Actually I think now its got to do with when I was compiling spine. I had to add a couple of symbolic links due to a mysql error it was throwing up (based on what I read from other posts in this forum). Specifically I added the two symlinks in red below and I think thats why its unable to read the database for the path_spine ?

relative: /usr/local/mysql/lib/mysql/libmysqlclient.so.12 -> libmysqlclient.so.12.0.0
relative: /usr/local/mysql/lib/mysql/libmysqlclient.so -> libmysqlclient.so.12.0.0
absolute: /usr/local/mysql/lib/mysql/libmysqlclient_r.a -> /usr/local/mysql/lib/mysql/libmysqlclient.a
absolute: /usr/local/mysql/lib/mysql/libmysqlclient_r.la -> /usr/local/mysql/lib/mysql/libmysqlclient.larelative: /usr/local/mysql-4.0.9/lib/mysql/libmysqlclient.so.12 -> libmysqlclient.so.12.0.0
relative: /usr/local/mysql-4.0.9/lib/mysql/libmysqlclient.so -> libmysqlclient.so.12.0.0
thank you

whew .. finally i was able fixed it ... i reran the ./configure --with-threadsafe (with threadsafe) on on my existing mysql distribution and just did a make and make install. Since i already had a database i didnt go any further.
I ensured my /etc/crontab was calling the poller every 5 mins and i was off and away. spine sure does run faster.

thanks

Of course this is NOT a good solution. What you, in fact need to do is make sure that your MySQL is recent enough to be copiled "thread safe".

The "_r" at the end of the library name is for a special build of MySQL Client libraries that allows Spine to operate safely in a multi-threaded capacity. Not using the correct libraries, may result in undesirable behavior.

To make MySQL "thread safe", you must compile the client library with the "--enable-thread-safe-client" flag.

Witness,
Thank you, I will do as you recommend.

However one question, with spine do I still need to use crontab to schedule running poller.php ?

I see this version of cacti runs multiple intervals to poll data from 30secs to 5 mins. So If i need some datasources to be polled say every 1 min, and others to be polled every 5 mins, then how do I configure my crontab ? (Shoud I configure it for 1 min and cacti will automatically run the 5 min data sources every 5 times the cron job runs? )

thank you.

Yes. Crontab is set to 300s. Rest is handled by cacti. Settings->Poller chooses the poller type: either cmd.php or spine
