===== Too many processes on {$HOSTNAME} =====

The Zabbix standard template for Linux has a constant value of 325 for the maximum number of processes that should run. On some systems, this is too low.

The solution is to change the constant to a **macro**. You can then use the default value for systems, but change it for individual machines if desired.

I created a macro named {$TRIGGER_THRESHOLD_PROCESSES_RUNNING}, then edited the //Template OS Linux// trigger to do this.
  - Administration | General | Macros
  - Add macro {$TRIGGER_THRESHOLD_PROCESSES_RUNNING} with value 325
  - Configuration | Templates | Template OS Linux | Triggers
  - In Template OS Linux, changed "Too many processes on {HOST.NAME}" trigger to "{Template OS Linux:proc.num[].last(0)}>{$TRIGGER_THRESHOLD_PROCESSES_RUNNING}"
  - Configuration | Hosts | your host name | Macros
  - Add Macro {$TRIGGER_THRESHOLD_PROCESSES_RUNNING} with value specific for that machine
  - Click Update

This allows you to customize individual machines.
