Snap collector plugin - mongodb
This plugin collects metrics from MongoDB database.
It's used in the Snap framework.
Getting Started
System Requirements
- golang 1.7+ - needed only for building
- mongodb 3.2.x
Operating systems
All OSs currently supported by Snap:
- Linux/amd64
- Darwin/amd64
Installation
Download the plugin binary:
You can get the pre-built binaries for your OS and architecture from the plugin's GitHub Releases page. Download the plugin from the latest release and load it into snapteld
(/opt/snap/plugins
is the default location for Snap packages).
To build the plugin binary:
Fork https://github.com/intelsdi-x/snap-plugin-collector-mongodb
Clone repo into $GOPATH/src/github.com/intelsdi-x/
:
$ git clone https://github.com/<yourGithubID>/snap-plugin-collector-mongodb.git
Build the Snap mongodb plugin by running make within the cloned repo:
$ make
This builds the plugin in ./build/
Configuration and Usage
-
Set up the Snap framework.
-
Configure connection strings to MongoDB service which includes username , password , hostname (default "localhost:27017").
-
Load the plugin and create a task, see example in Examples.
Documentation
This collector gathers metrics from mongodb server status command.
Global config
Global configuration files are described in Snap's documentation. You have to add "mongodb"
section with following entries:
"uri"
- it's hostname and port pair in format"hostname:port"
, as default set to"localhost:27017"
."username"
- username if authentification is enabled"password"
- password if authentification is enabled
See exemplary Global configuration files in [examplary config files] (examples/configs/).
Collected Metrics
List of collected metrics is described in METRICS.md.
Examples
Example of running Snap mongodb collector and writing data to file.
Ensure snap daemon is running:
- initd:
service snap-telemetry start
- systemd:
systemctl start snap-telemetry
- command line:
snapteld -l 1 -t 0 &
Download and load Snap plugins:
$ wget http://snap.ci.snap-telemetry.io/plugins/snap-plugin-collector-mongodb/latest/linux/x86_64/snap-plugin-collector-mongodb
$ wget http://snap.ci.snap-telemetry.io/plugins/snap-plugin-publisher-file/latest/linux/x86_64/snap-plugin-publisher-file
$ chmod 755 snap-plugin-*
$ snaptel plugin load snap-plugin-collector-mongodb
$ snaptel plugin load snap-plugin-publisher-file
