This plugin monitors openstack nova resources such as limits, quotas and hypervisors.
Plugin retrieves statistics using Nova Compute v2 Rest API.
- golang 1.6+ - needed only for building
All OSs currently supported by snap:
- Linux/amd64
You can get the pre-built binaries for your OS and architecture at plugins's GitHub Releases page. Download the plugins package from the latest release, unzip and store in a path you want snaptel to access.
Fork https://github.com/intelsdi-x/snap-plugin-collector-nova
Clone repo into $GOPATH/src/github.com/intelsdi-x/:
$ git clone https://github.com/<yourGithubID>/snap-plugin-collector-nova.git
Build the plugin by running make within the cloned repo:
$ make
This builds the plugin in ./build/
- Set up the snap framework.
- Create Global Config, see description in snap's Global Config.
- Load the plugin and create a task, see example in Examples.
Configuration for this plugin is given via global config. Global configuration files are described in snap's documentation. You have to add section "nova-compute" in "collector" section and then specify following options:
"openstack_user"- user name used to authenticate (ex."admin"),"openstack_pass"- password used to authenticate (ex."admin"),"openstack_tenant"- tenant name used to authenticate (ex."admin"),"openstack_auth_url"- keystone url (ex."http://172.16.0.5:5000/v2.0/").
These values should correspond to values given in nova.conf:
"allocation_ratio_cores"- oversubscription ratio for vcpus, used to derive some metrics for hypervisors (ex. 1.5),"allocation_ratio_ram"- oversubscription ratio for memory, used to derive some metrics for hypervisors (ex. 3),"reserved_node_cores"- reserved virtual cores, used to derive some metrics for hypervisors (ex. 2),"reserved_node_ram_mb"- reserved virtual memory, used to derive some metrics for hypervisors (ex. 2048).
Example global configuration file for snap-plugin-collector-nova plugin (exemplary file in [examples/cfg/] (examples/cfg/)):
{
"control": {
"plugins": {
"collector": {
"nova-compute": {
"all": {
"openstack_auth_url": "http://localhost:5000/v2.0/",
"openstack_user": "admin",
"openstack_pass": "admin",
"openstack_tenant": "admin",
"allocation_ratio_cores" : 1.5,
"allocation_ratio_ram": 3,
"reserved_node_cores" : 2,
"reserved_node_ram_mb" : 2048
}
}
},
"publisher": {},
"processor": {}
}
}
}
List of collected metrics is described in METRICS.md.
Example running nova collector and writing data to a file.
Create or download example global config on snapteld's node:
mkdir -p /etc/snap/
curl -sfLO https://github.com/intelsdi-x/snap-plugin-collector-nova/blob/master/examples/cfg/cfg.json -o /etc/snap/snapteld.conf
Ensure snap daemon is running:
- initd:
sudo service snap-telemetry start - systemd:
sudo systemctl start snap-telemetry - command line:
sudo snapteld -l 1 -t 0 &
Download and load snap plugins:
$ wget http://snap.ci.snap-telemetry.io/plugins/snap-plugin-collector-nova/latest/linux/x86_64/snap-plugin-collector-nova
$ wget http://snap.ci.snap-telemetry.io/plugins/snap-plugin-publisher-file/latest/linux/x86_64/snap-plugin-publisher-file
$ snaptel plugin load snap-plugin-collector-nova
$ snaptel plugin load snap-plugin-publisher-file
See available metrics for your system
$ snaptel metric list
Download an example task file and load it:
$ curl -sfLO https://github.com/intelsdi-x/snap-plugin-collector-nova/blob/master/examples/tasks/task.json
$ snaptel task create -t task.json
