An excellent tool ! It was decided to use Cacti as a replacement for a commercial tool in our company.

We are running Cacti as follows :

Database/polling server

2 x 2.7GHz Xeon,
Suse Linux 8.2 under VM/ESX server,
4GB RAM ( usable : 3.6GB )
Disks 1x18GB, 1x36GB
IHS Webserver 2.0.42.1 ( IBM, based on Apache )
RRDTool 1.0.49
MySQL 4.0.24
PHP 4.3.8
Cacti 0.8.6g
Cactid 0.8.6f

This server is running MySQL, RRDTool, and polling. Administration & presentation access ( for "normal" user - approx. 200 registered ) is realized through separate servers, connected via a shared WAN link 120 Mbit/s

MySQL tuning :
key_buffer = 32M
max_allowed_packet = 1M
table_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
myisam_sort_buffer_size = 8M
max_connections = 4000
query_cache_size=64M

Presentation server

1 x 1.7GHz Xeon,
Suse Linux 8.2 under VM/ESX server,
1GB RAM
IHS Webserver 2.0.42.1 ( IBM, based on Apache )
MySQL 4.0.24, connected to the Database/polling server
PHP 4.3.8
Cacti 0.8.6g
RRDTool is connected via NFS mount


Administration server

1 x 2.8GHz P4
Suse Linux 8.2
1GB RAM
IHS Webserver 2.0.42.1 ( IBM, based on Apache )
MySQL 4.0.24, connected to the Database/polling server
PHP 4.3.8
Cacti 0.8.6g
RRDTool is connected via NFS mount

Polling statistics ( 1 extract )

12/15/2005 02:22:38 PM - SYSTEM STATS: Time:157.5933 Method:cactid Processes:6 Threads:30 Hosts:1479 HostsPerProcess:247 DataSources:46797 RRDsProcessed:23972

The network devices are located all around the world, connected through WAN links with 2 - 155 Mbit/s. The devices are mainly layer 3 router, currently only traffic I/O and CPU usage is monitored. Long term it is intended to include all our layer 2 devices as well but that will most probably require the distributed polling support promised for Cacti 0.9x .

On the presentation server we have linked - into Cacti as a separate tab - the Network Weathermap ( Howie 's php-weathermap-0.6 ) for the global core links.

Please, don't ask for which company we are working - its a big global player, that's all we are allowed to say.

Problems so far
  • the presentation of data / charts is a bit slow - we need better hardware for the presentation and a faster link to the database / polling server. We will also try to improve the performance by separating database & polling on different servers with a 1 Gbit/s connection ( at least ) together with improved hardware ( more CPU's & more RAM ).
Feature requests
  • we are missing some sort functions in the tables for devices & user management
  • users would like to customize the time zone to view the results ( data collection is based on GMT/UTC of course )
For any questions contact either myself ( Oldie ) or Frizz.

Hi Oldie

did you use MySQL replication between your database and presentation server ?

Fmangeant,
no, only with directed SQL requests via TCP.
We´re using a single database without replication.
Do you have operating experience with a replicated database and Cacti?

cactid poller stats

Post by thomasw »

Great peace of work!

Here our experience about cacti-scaling

2 x fsc-blade servers ( 1 LAN / 1 WAN) running cacti on the following hardware:

-dual xeon 3,2 ghz (hyperthreading)
- 4 GB RAM
- 36 GB SCSI RAID-1 U-320

- 2x1000 NIC (1xpoller,1xweb)

Debian Linux 3.1 with Kernel 2.6.14.3 as OS

The poller statistics from the LAN Manager (using 1,1GB RAM):
12/22/2005 10:35:11 AM - SYSTEM STATS: Time:9.3620 Method:cactid Processes:4 Threads:8 Hosts:55 HostsPerProcess:14 DataSources:11774 RRDsProcessed:5887

The poller statistics from the WAN manager (using 1,8GB RAM):
12/22/2005 11:00:46 AM - SYSTEM STATS: Time:45.1819 Method:cactid Processes:4 Threads:16 Hosts:757 HostsPerProcess:190 DataSources:5019 RRDsProcessed:2491

I`m very impressed about the poller runtime, really a great peace of work!!

Hope somebody can use the informations on scaling his cacti installation...

Heyalp!

Specs of system:

Dell Optiplex GX280, 512Mb Ram, 2.4Ghx processor, enough disk space, but only a desktop PC...
No longer a n00by, probably, by now an 0ldby

Now Head of Technology at RSCH, back to the prickly subject of Monitorring....

8x improvement. Very impressive!

Server is a basic PIII-1Ghz with 512Mb. It's also running our (fairly busy) Request Tracker installation at the moment.
Weathermap 0.98a is out! & QuickTree 1.0. Superlinks is over there now (and built-in to Cacti 1.x).
Some Other Cacti tweaks, including strip-graphs, icons and snmp/netflow stuff.
(Let me know if you have UK DevOps or Network Ops opportunities, too!)

The biggest speed boost I got was going from RRDTool 1.0.49 to 1.2.12
(aside from switching from CMD.php to Cactid)

My production server:
FreeBSD v5.4 on a Pentium 4 3.0Ghz 1Gb RAM (Soft mirrored 160GB HD)
PHP v5.0.5
Apache v2.0.55
MySQL v4.14
Net-SNMP v5.3.0.1
Cacti v0.8.6h
Cactid v0.8.6g

I am thinking of upgrading my production server to FreeBSD v6.
Unfortunately I am not confident in my ability to backup my Cacti and MySQL and be able to restore it on another OS.

Is there a one-stop backup plugin or utility (or guide) out there?
Also I like to run on MySQL v5.0.18 upgrading and migrating my existing data from my current 4.x MySQL.
Thank you,

Ernie
