Fixing GAPS

[Zombie]

Server
Fedora release 7 (Moonshine)
cacti-0.8.7b
CMD.PHP
rrdtool.i386 1.2.27-1.fc7
----------
I've been using this server with no problem for 1 year after that I started to see GAPS on the graphs from time to time >> only one cron is running

I tried to move to spine but after configuring and changing to spine the graph stop updating when I turn back to CMD.PHP it starts working

You can bump the number of concurrent processes. Right now you only have a 1 way process. Not good as in interim. You can easily go 2+ the number of cores.

can you please tell me the way of doing the above step ... appreciating your great effort

error after changing to spine

Hosts:441 HostsPerProcess:441 DataSources:12106 RRDsProcessed:0

then the rrd increases ..... RRDsProcessed:168 and that's it

is there any other solution

[TheWitness]

If the spine version is G and Cacti is before that release, there is a PRE-G variable that must be set in spine.conf.

Don't have enough details to go further.

yes I configured spine 0.8.7 g on cacti-0.8.7b version

and i have
Frdora core 7 32 bit

7 processor
Intel(R) Xeon(R) CPU E5420 @ 2.50GHz

Mem 8GB

can you please specify what is the best values for

Maximum Concurrent Poller Processes

Maximum Threads per Process

Number of PHP Script Servers

The Maximum SNMP OID's Per SNMP Get Request

thank you

[TheWitness]

Run spine in read only mode and make sure its running. Apply the G patches to.

[Zombie]

Spine is running but the rras seems to be conflicting with old ones.


anyhow I'll keep using CMD.PHP but can you tell me what will be the best value of Concurrent Poller Processes to choose for my architecture as I bump the processes to 8 as shown below

Fedora Core 7 32 bit
8 Processors Intel(R) Xeon(R) CPU E5420 @ 2.50GHz
8Gb RAM

Code: Select all
