Cacti - Scalability

[pto]

Hi,
We are currently using cacti for our IP core network, and we are planning to add more IP nodes.
I have been been searching on the net on the cacti forum for recommendations how to scale cacti, but I have not found anything usefull.

We are experiencing gaps in the graphs and I think its because the poller takes too long to execute. I guess that the polling times must be less that the polling periode (5 min = 300 sec).

Can someone give me a suggestion how to improve performance?

Have you looked at spine?

Hi again

We are using spine for polling. However, i am still worried about the cacti scalablity.

Are you using scripts to a great extend? 120 hosts and about 10.000 ds is nothing to worry about in general. We are running 5 times that amount on hw as old as 6 years. If rrdtool update (aka disk performance) is an issue, boost will help. But in general, that low amount of ds is not yet the level were boost comes in.
