++ Some graphs not showing/Segmentation Fault ++

[maiden]

I have problem about graph, sometime some no data on graph, I found log as below.


SPINE: Poller[0] FATAL: Spine Encountered a Segmentation Fault (Spine thread)
POLLER: Poller[0] Maximum runtime of 298 seconds exceeded. Exiting.
SYSTEM STATS: Time:299.2490 Method:spine Processes:8 Threads:16 Hosts:422 HostsPerP rocess:53 DataSourc es:3175 RRDsProce ssed:1440

Processes:8 Threads:16 = too high. Processes should be 2 x the amount of cores you have

Try with Processes:2 and around 10 threads, and see where that leads.

Thank for your suggestion.

My server:
Processes 4 Cores Intel(R) Xeon(R) CPU X3370 @ 3.00GHz
Memory 4G

And I try with processes 2 and 10 thread but log still has Spine Encountered a Segmentation Fault

I already compile and found this log, I don't know that was cause of error or not.
configure: error: Cannot find MySQL headers. Use --with-mysql= to specify non-default path.

After that I found your suggestion in other forum for this error should be install mysql-devel, I already install it and the log in attach file. Thanks.


When I restart mysqld, why I saw log as below, (Iused spine not cmd.php)

How many connections for your database. You are a bit abusive. Too many processes + theads.

Equation is:

Max MySQL Connections = some value larger than:

Processes * (Threads + Script Servers) + 1

Therefore,

10 Script Servers
10 Processes
20 Threads

Results in:

10 * (30) + 1 == 301 Just to poll. Only a Cacti system with > 10k devices should require something like that, and only on some pretty fast hardware where the DB is separate from the poller.

Dear TheWitness
I changed poller information to 5 script servers, 6 processes and 10 threads, but I still found log as below, how to fix this problem.
thank you.

Run a test from the command line:

Code: Select all

./spine -R -V 5

Hi TheWitness

The result after run cmd in attach file.
Thank you.

[TheWitness]

ok, now the following:

Code: Select all

./spine -R -V 5 -f 362 -l 362

TheWitness

[maiden]

ok, now the following:

Code: Select all

./spine -R -V 5 -f 362 -l 362

TheWitness

Now I already run that cmd.
Thank you.

I would like to know about calculation appropriately of the parameter for tunning cacti such as

1.Maximum Concurrent Poller Processes (as I know=Core CPU*2)
2.Maximum Threads per Process
3.Number of PHP Script Servers
4.Script and Script Server Timeout Value
5.The Maximum SNMP OID's Per SNMP Get Request
6.Mysql max_connection (you told me=Processes * (Threads + Script Servers) + 1 )

Note :
1. CPU 4Core 3G
2. RAM 4G
3. HDD 300G
4. In the future 500-700 devices + (datasource about 3500+)
5. CentOS 5.4, spine 0.8.7e, cacti 0.8.7e,weathermap v0.97


!!! I confuse about poller because I used spine not cmd.php but, when I setting log in "DEVEL-Developer Debug level" the log as below: show poller cmd.php not spine. What is something wrong in my server ?The poller is wrong or not?

[maiden]

Dear Thewitness

I used cmd for test script server:

php /var/www/html/cacti/script_server.php
PHP Script Server has Started - Parent is cmd

actually I used spine not cmd, this is wrong or not ?
