Infoblox custom meters for Ceilometer (Liberty)

Project description

Infoblox Custom Meters for Ceilometer

This package provides files used by OpenStack Ceilometer to monitor various DNS and DHCP metrics from Infoblox NIOS instances. With this package installed and configured, the Ceilometer Compute Agent will poll local NIOS instances via SNMP, and store the results as samples with metric names starting with ‘nios.dns’ and ‘nios.dhcp’.

  • Free software: Apache license


This module enables SNMP polling of NIOS instances to collect DNS and DHCP metrics.

OpenStack Configuration

After installing the package, you must configure Ceilometer with the SNMP credentials, as well as tell it how to reach the NIOS machines.

Since the Ceilometer agent is running within the address space of the host node, the grid member IP address used must be reachable from the host. This can be done by allocating the IP on an external network, or by using a floating IP.

By default, the first floating IP for a given instance will be used for SNMP access. To override this behavior, you can set a infoblox-snmp-ip metadata value on the instance.

Similarly, you may set the default SNMP community, password, and port in a [infoblox] stanza within the ceilometer.conf file, or you can set them on a per-instance basis using instance metadata.

The table below summarizes the different options.

Config File Variable Instance Metadata Name Description
metadata_name N/A The name of the instance metadata item used to identify an instance as an Infoblox DDI appliance. Default value is infoblox.
N/A infoblox-snmp-ip By default the first floating IP found is used; set this value on the instance to specify a particular IP to be used for SNMP access.
snmp_community_or_username infoblox-snmp-community The SNMP community for v2c, or the user name for SNMPv3. The default value is public.
snmp_password infoblox-snmp-password The SNMP password for SNMPv3.
snmp_port infoblox-snmp-port The port to use for SNMP polling. Default value is 161.

You must also configure the security groups to allow UDP traffic to port 161 on the NIOS instances, from the host IP network.

Infoblox NIOS Configuration

You must enable SNMP for the grid or for the specific members which you would like to poll. This is done in the Grid > Grid Manager screen, using the Grid Properties button on the right-hand toolbar. This brings up an editor from which you can select SNMP, enable it, and enter a community string.

Currently only SNMPv2c is tested.
