Getting Started

System Requirements

• golang 1.7+ (needed only for building)

Operating systems

All OSs currently supported by snap:

• Linux/amd64

Installation

Download logs-openstack 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-processor-logs-openstack

Clone repo into $GOPATH/src/github/intelsdi-x/:

$ git clone https://github.com/<yourGithubID>/snap-plugin-processor-logs-openstack

Build the plugin by running make in repo:

$ make

This builds the plugin in ./build

Configuration and Usage

• Set up the Snap framework

Documentation

Openstack Log Pattern

The Openstack log is expected to be in this form:

    <timestamp> <pid> <severity_label> <python_module> <payload>

Example:

    2016-12-07 03:53:55.873 24 INFO nova.osapi_compute.wsgi.server _some_message_

Find out more about Openstack logs pattern in LOG_PATTERNS.md

Openstack Log Processing

The intention of this plugin is parsing Openstack logs provided by snap-plugin-collector-logs as metric's data to process them to producing these values:

• timestamp which replaces metric's timestamp
• pid
• severity_label and severity where:
  • "EMERGENCY" -> 0
  • "ALERT" -> 1
  • "CRITICAL" -> 2
  • "ERROR" -> 3
  • "WARNING" -> 4
  • "NOTICE" -> 5
  • "INFO" -> 6
  • "DEBUG" -> 7
• python_module
• payload which replaces metric's data
• others request-context related (if occur in payload):
  • request_id
  • tenant_id
  • user_id
  • http_method
  • http_url
  • http_version
  • http_status
  • http_response_size
  • http_response_time
  • http_client_ip_address
• and logger in form "openstack.<service_name>", where the service_name is determined in incoming metric's namespace as a log_file (see snap-plugin-collector-logs#collected-metrics).

How it works

For example, for the following metric which is input provided by snap-plugin-collector-logs:

Before processing:

• Namespace: /intel/logs/openstack/nova-api.log/metrics
• Timestamp: 2016-12-07T10:23:13.509335257+1:00,
• Data:
  "2016-12-07 03:53:55.873 24 INFO nova.osapi_compute.wsgi.server [req-0c0b761c-47b0-4bf5-832c-89ef048fa56a fa2b2986c200431b8119035d4a47d420 b1ad1df9062a4fc682904c6c9b0f4e98 - default default] 10.91.126.38,10.0.0.1 \"GET /v2.1/b1ad1df9062a4fc682904c6c9b0f4e98/extensions HTTP/1.1\" status: 200 len: 23011 time: 0.4711170"
• Tags: - "plugin_running_on": "your-hostname"

• Namespace: /intel/logs/openstack/nova-api.log/metric

Examples

This is an example running snap-plugin-collector-logs, processing collected openstack-logs and writing post-processed data to a file. It is assumed that you are using the latest Snap binary and plugins. The example is run from a directory which includes snaptel, snapteld, along with the plugins and task file.

In one terminal window, open the Snap daemon (in this case with logging set to 1 and trust disabled) with appropriate configuration needed by logs collector. To do that properly, please follow the instruction on snap-plugin-collector-logs.

$ snapteld -l 1 -t 0 --config config.json

In another terminal window:

Download logs collector plugin:

$ wget http://snap.ci.snap-telemetry.io/plugins/snap-plugin-collector-logs/latest/linux/x86_64/snap-plugin-collector-logs

Load logs collector plugin:

$ snaptel plugin load snap-plugin-collector-logs
Plugin loaded
Name: logs
Version: 1
