CACTI capaability for 3000 network devices

#1 Post by ponnuchelvam » Fri Sep 28, 2018 7:05 am

Hi team, We are planned to migrate our Network devices to CACti monitoring system. Count might comes around 3000+. May we know CACTI is suiteable for the scale?. Can we acheive these count using MAin and Remote Poller architecure(distribution). If possible, may we know the hardware size for the product. Please advise. We are new for this product.

Thanks and Regards

For that number of devices, it is recommended to use a remote poller setup. You should probably consider the 1.2 beta release that's coming because it has improvements for storing the remote poller data local to that poller, then synchronising back to the main poller.

If using 5 minute collection, I know sites with over 25k devices. Use SSD/NVMe for the database and RRDfile partitions, boost and spine. 3k is a cake walk be it remote or central data collection at 5 minutes. If using one minute, start with 1.2 and leverage as many remote data collectors as it takes. Remote data collectors will enable horizontal scaling starting with that version as netniv suggests.

Thanks netniV and Osiris for your response. Exactly, we are planning to have horizantal distribution setup. Then, i can go with 5min pollin interval. May I have Main Poller VM and Remote poller VM sizing ?. can we configure DB in separate VM?.

Total device : 3000 +
1 main poller

5 remote poller , each poller should increase upto 800+ devices.

Please share best architecture for the above counts, if you have.

Thanks and Regards
