[[en:documentation:pandorafms:introduction:01_introduction|Pandora FMS]] is a complex distributed application that has different key elements, susceptible to represent a bottleneck if it is not sized and configured correctly. The purpose of this chapter is to help to carry out a capacity study, **to analyze the //scalability// of Pandora FMS according to a specific set of parameters**. This study will help to know the requirements that the installation should have to be able to support a certain capacity.

An installation of Pandora FMS with a GNU/Linux server installed "by default" in a powerful machine, can not pass from 5 to 6 packets per second, in a powerful machine well "optimized" and "conditioned" it can reach 30 to 40 packets per second. **This also depends a lot on the number of modules in each agent**.

Obviously, the more threads you have, the more checks you will be able to execute. If you add all the threads that Pandora FMS executes, they should not reach the range of 30 to 40. You should not use more than 10 threads here, although it depends a lot on the type of hardware and the GNU/Linux version you are using.

明らかに、スレッドが多いほど、実行できるチェックも多くなります。 Pandora FMS が実行するすべてのスレッドを追加しても、30〜40 を超えることはありません。利用している Linux バージョンとハードウェアの種類に大きく依存しますが、ここでは 10 を超えるスレッドは使用するべきではありませn。

Now, you must "create" a fictitious number of ping type modules to test. It is assumed that you will test a total of 3000 ping modules. To do this, it is best to take a system on the network that is capable of supporting all pings (any GNU/Linux server can handle the task).

This is specifically about the SNMP Enterprise network server. In case of testing for the Open network server, see the section on the (generic) network server.

This is the SNMP network server. Assuming you already have the server up and running and configured. Some key parameters for its operation:
It defines the number of SNMP requests that the system will do for each execution. You should consider that the server groups them by destination dir IP, so this block is only indicative. It is recommendable that it wouldn't be large (30 to 40 maximum). When an item of the block fails, an internal counter does that the Enterprise server will try it again, and if after x attempts it doesn't work, then it will pass it to the open server.
+
It defines the number of SNMP requests that the system will make for each execution. Bear in mind that the server groups them by destination IP address, so this block is a guideline. It should not be too large (30 to 40 maximum). When a block element fails, an internal counter causes the PFMS server to retry it.

これは、システムが 1回に実行する SNMP リクエストの数を定義します。サーバが宛先 IP でグループ化することを考慮するため、このブロックは単なる指標です。 大きくしないことをお勧めします(最大 30〜40)。ブロック内の要素に障害が発生すると、内部カウンターは Enterprise サーバでそれを再試行し、試行回数が x 回を超えても応答がない場合は、オープンソースのサーバに処理を渡します。
It should not be too large (30 to 40 maximum). When an element of the block fails, an internal counter makes the Enterprise server retry it, and if after X attempts it does not work, it will be passed to the Open server. You shouldn't user more than 10 threads, though it depends on the kind of hardware and GNU/Linux version that you use.

当然ですが、スレッド数が多いほど実行できるチェックの数も増えますが、Pandora FMS が実行するすべてのスレッド数を合計しても 30~40 の範囲にはならないようにします。ハードウェアの種類や Linux のバージョンによって大きく異なりますが、ここでは 10 を超えるスレッド数は使用しないでください。
The faster way to test is through a SNMP device, applying all the interfaces, all the serial "basic" monitoring modules.This is done through the application of the Explorer SNMP (Agente → Modo de administracion → SNMP Explorer). Identify the interfaces and apply all the metrics to each interface. In a 24 port switch, this generates 650 modules.
