Can the appliance capacity be increased to more than 100 devices?

According to this document these are the limits.

If you increased the cores & memory, buffer sizes etc would it perform like a regular install of Zabbix?

Number of hosts/devices is less important.
More important is number of metrics, sampling rate of those metrics.
Zabbix used SQL database backend and bandwith of wreatten data to this DB backend depends on hardware spec on which OS with zabbix services is running.

In other words: it is not possible to answer precisely on question on which answer depends not on zabbix per se but on few other factors.
It may be "a small difference" if you will be monitoring one metrics a day per you device and thousand metrics per second on every your device. Isn't it?

Point taken on the number of hosts vs metrics per host.

In which case my question is, why is the appliance rated at 1/5 to 1/10th the capacity of a non appliance install and can the appliance capacity be increased?

Thanks

Hi Mmacpuguy!
Kloczek just want say, - performance does not depends so much from number of hosts monitored. It depends how many items you want to collect per second.

My answer would be - yes, can increase.
Bottleneck usually, - performance of database storage and connection between Zabbix server and the database.
If you have powerful enough hardware, can tune MySQL and Zabbix server conf and capacity can be increased.

If you will install Virtual appliance using Packages, you will get approximately the same result. Anyway you will need to tune MySQL and Zabbix server configuration.
In regards of database, some changes is better to do before creation of Zabbix database, so Package installation can be better.

To get more detailed information, what kind of Hardware/Software you need:
1. Try to make some inventory, how many Items you will collect per device?
2. What type of items will be (numeric / text)?
3. How many devices you want to monitor?
4. How many locations you have and connection speed between sites (if applicable)

Paste this information to forum or write to [email protected] and you will get required info.

Best regards,
Alexander

Sure. Just change the virtual hardware you give it.
