# RavenDB Server

## Overview

Zabbix template for RavenDB via SNMP.

### Usage

- Please modify the macros to match your instance specifications and your workload. Recommended values are:
- `MANAGED_MEMORY_RECOVERY_THRESHOLD` around 65% of total machine RAM
- `MANAGED_MEMORY_THRESHOLD` around 75% of total machine RAM
- `UNMANAGED_MEMORY_THRESHOLD` around 25% of total machine RAM

## Authors

Grzegorz Lachowski

Bartosz Piekarski

## Macros used

|Name|Description|Default|
|---|---|---|
| {$MANAGED_MEMORY_RECOVERY_THRESHOLD} | Managed memory recovery threshold | 2.5G |
| {$MANAGED_MEMORY_THRESHOLD} | Managed memory threshold | 3G |
| {$UNMANAGED_MEMORY_THRESHOLD} | Unmanaged memory threshold | 1G |
