Overview
The LMA Infrastructure Alerting Plugin is used to install and configure Nagios™ which provides the alerting and escalation functionalities of the LMA Toolchain.
Nagios is a key component of the LMA Toolchain project as shown in the figure below.
Requirements
| Requirement | Version/Comment |
|---|---|
| Disk space | The plugin's specification requires to provision at least 15GB of disk space for the system, 10GB for the logs and 20GB for Nagios™. As a result, the installation of the plugin will fail if there is less than 45GB of disk space available on the node. |
| Fuel | Mirantis OpenStack 8.0 |
| The LMA Collector Fuel Plugin | v 0.9 |
| The LMA InfluxDB Grafana Fuel Plugin | v 0.9 This is optional and only needed if you want to create alarms in Nagios™ for time-series stored in InfluxDB. |
| Hardware configuration | The hardware configuration (RAM, CPU, disk) required by this plugin depends on the size of your cloud environment and other parameters like the retention period of the data. A typical setup would at least require a quad-core server with 8GB of RAM and fast disks (ideally, SSDs). |
Limitations
If Nagios is installed on several nodes for high availability, the alerts history will be lost in case of a server failover.
