面白そうな記事を見つけたのでインストールしてみました｡

Installation
https://github.com/firehol/netdata/wiki/Installation
環境
･CentOS Linux release 7.5.1804 (Core)
･Kerne: 3.10.0-862.3.3.el7.x86_64
･Apache/2.4.6 (CentOS)
Apacheのインストールは省略します｡
- Mod_Statusモジュールの有効化
- server-statusの有効化
- Apache再起動
- server-statusの動作確認
- Netdataのインストール
- Netdataの設定ファイル
- NetdataでApacheパフォーマンスの確認

localhostからのみ許可しています｡

スクリプトが実行されてプログラムのダウンロード､環境チェックが行われます｡

# bash <(curl -Ss https://my-netdata.io/kickstart.sh) System : Linux Operating System : GNU/Linux Machine : x86_64 BASH major version: 4 (snip) |
今回は下記のメッセージが表示されました｡
おそらくそのままENTERでyumが実行されるのではと思ったのですが､一度スクリプトを停止して個別にyum install PyYAML autogen libmnl-devel libuuid-develを実行しました｡

The following command will be run: >> IMPORTANT << Please make sure your system is up to date by running: yum update yum install PyYAML autogen libmnl-devel libuuid-devel Press ENTER to run it > |

# yum install PyYAML autogen libmnl-devel libuuid-devel |
改めてインストールスクリプトを実行します｡
必要なパッケージのインストールが確認され､プログラムのダウンロード､コンパイルが実行されます｡

Now proceed to the next step. OK (snip) netdata by default listens on all IPs on port 19999, so you can access it with: http://this.machine.ip:19999/ To stop netdata run: systemctl stop netdata To start netdata run: systemctl start netdata Uninstall script generated: ./netdata-uninstaller.sh Update script generated : ./netdata-updater.sh netdata-updater.sh can work from cron.

cronで毎日アップデートスクリプトの実行設定まですべてインストール時に行われます｡
localhostでApacheが動作しているなら取り敢えずそのままで動作します｡

# cat /etc/netdata/python.d/apache.conf # netdata python.d.plugin configuration for apache # # This file is in YaML format. Generally the format is: # # name: value # # There are 2 sections: # - global variables # - one or more JOBS # # JOBS allow you to collect values from multiple sources. # Each source will have its own set of charts. # # JOB parameters have to be indented (using spaces only, example below). # ---------------------------------------------------------------------- # Global Variables # These variables set the defaults for all JOBs, however each JOB # may define its own, overriding the defaults. # update_every sets the default data collection frequency. # If unset, the python.d.plugin default is used. # update_every: 1 # priority controls the order of charts at the netdata dashboard. # Lower numbers move the charts towards the top of the page. # If unset, the default for python.d.plugin is used. # priority: 60000 # retries sets the number of retries to be made in case of failures. # If unset, the default for python.d.plugin is used. # Attempts to restore the service are made once every update_every # and only if the module has collected values in the past. # retries: 60 # autodetection_retry sets the job re-check interval in seconds. # The job is not deleted if check fails. # Attempts to start the job are made once every autodetection_retry. # This feature is disabled by default. # autodetection_retry: 0 # ---------------------------------------------------------------------- # JOBS (data collection sources) # # The default JOBS share the same *name*. JOBS with the same name # are mutually exclusive. Only one of them will be allowed running at # any time. This allows autodetection to try several alternatives and # pick the one that works. # # Any number of jobs is supported. # # All python.d.plugin JOBS (for all its modules) support a set of # predefined parameters. These are: # # job_name: # name: myname # the JOB's name as it will appear at the # # dashboard (by default is the job_name) # # JOBs sharing a name are mutually exclusive # update_every: 1 # the JOB's data collection frequency # priority: 60000 # the JOB's order on the dashboard # retries: 60 # the JOB's number of restoration attempts # autodetection_retry: 0 # the JOB's re-check interval in seconds # # Additionally to the above, apache also supports the following: # # url: 'URL' # the URL to fetch apache's mod_status stats # # if the URL is password protected, the following are supported: # # user: 'username' # pass: 'password' # ---------------------------------------------------------------------- # AUTO-DETECTION JOBS # only one of them will run (they have the same name) localhost: name : 'local' url : 'http://localhost/server-status?auto' localipv4: name : 'local' url : 'http://127.0.0.1/server-status?auto' localipv6: name : 'local' url : 'http://::1/server-status?auto' |
