うろ覚えを無くしていこうともがき苦しむ人の備忘録

Mackerel事始め agent-plugin EC2関連

mackerel AWS

agent-pluginを使ってEC2関連の監視設定を追加していきます。

IAM Policy設定

CloudWatch経由の取得のため GetMetricStatistics を IAMrole または IAMuser へ付与します。

  • cloudwatch:GetMetricStatistics
  • IAM role で設定されていれば access-key-id、secret-access-key の指定は不要

CPU credit

  • mackerel-plugin-aws-ec2-cpucredit

aws-ec2-cpucredit.conf

# mackerel-plugin-aws-ec2-cpucredit [-instance-id=<id>] [-region=<aws-region>] [-access-key-id=<id>] [-secret-access-key=<key>] [-tempfile=<tempfile>]

[plugin.metrics.aws-ec2_cpucredit]
command = "/usr/local/bin/mackerel-plugin-aws-ec2-cpucredit -access-key-id AWS_ACCESS_KEY_ID -secret-access-key AWS_SECRET_ACCESS_KEY"

volume-id がメトリクス名として設定されてしまうため、同一グラフ上でまとめて表示させるには一手間掛かりそうです。
ホスト単位であれば複数ボリュームを纏めて表示できるようなので別途考えたいと思います。

mackerel-plugin-linux

  • type オプションのデフォルトはall
GLOBAL OPTIONS:
   --tempfile, -t "/tmp/mackerel-plugin-linux"  Set temporary file path. [$ENVVAR_TEMPFILE]
   --type, -p "all"             Select metrics: all, swap, netstat, diskstats, proc_stat, users [$ENVVAR_TYPE]
   --help, -h                   show help
   --version, -v                print the version

linux.conf

[plugin.metrics.linux]
command = "/usr/local/bin/mackerel-plugin-linux"
type = "metric"
