如何configuration敏感keepalive警告松懈
我想发出一个松懈的警报。 当一个客户失败时，保持活着的检查。
这个过程是什么？ 我可以知道怎么做吗？ 我正在使用hiroakis/docker-sensu-server镜像。
在懒散的一面：
在闲置的一面，你必须创build一个新的传入webhook到你想要的频道。
在感觉方面：
你创build一个使用webhook的新处理程序。
那么你必须分配这个处理程序来用于你在他们的检查configuration文件中需要的检查。
如果你需要一个代理连接到互联网，请记住把它放在处理程序中，或者以更优雅的方式通过configuration文件传递它。
例如。 你可以使用这个处理程序：
#!/usr/bin/env ruby # Copyright 2014 Dan Shultz and contributors. # # Released under the same terms as Sensu (the MIT license); see LICENSE # for details. # # In order to use this plugin, you must first configure an incoming webhook # integration in slack. You can create the required webhook by visiting # https://{your team}.slack.com/services/new/incoming-webhook # # After you configure your webhook, you'll need the webhook URL from the integration. require 'rubygems' if RUBY_VERSION < '1.9.0' require 'sensu-handler' require 'json' class Slack < Sensu::Handler option :json_config, description: 'Configuration name', short: '-j JSONCONFIG', long: '--json JSONCONFIG', default: 'slack' def slack_webhook_url get_setting('webhook_url') end def slack_channel get_setting('channel') end def slack_proxy_addr get_setting('proxy_addr') end def slack_proxy_port get_setting('proxy_port') end def slack_message_prefix get_setting('message_prefix') end def slack_bot_name get_setting('bot_name') end def slack_surround get_setting('surround') end def markdown_enabled get_setting('markdown_enabled') || true end def incident_key @event['client']['name'] + '/' + @event['check']['name'] end def get_setting(name) settings[config[:json_config]][name] end def handle description = @event['check']['notification'] || build_description post_data("*Check*\n#{incident_key}\n\n*Description*\n#{description}") end def build_description [ @event['check']['output'].strip, @event['client']['address'], @event['client']['subscriptions'].join(',') ].join(' : ') end def post_data(notice) uri = URI(slack_webhook_url) if (defined?(slack_proxy_addr)).nil? http = Net::HTTP.new(uri.host, uri.port) else http = Net::HTTP::Proxy(slack_proxy_addr, slack_proxy_port).new(uri.host, uri.port) end http.use_ssl = true begin req = Net::HTTP::Post.new("#{uri.path}?#{uri.query}") text = slack_surround ? slack_surround + notice + slack_surround : notice req.body = payload(text).to_json response = http.request(req) verify_response(response) rescue Exception => e puts "An error has ocurred when posting to slack: #{e.message}" end end def verify_response(response) case response when Net::HTTPSuccess true else fail response.error! end end def payload(notice) { icon_url: 'http://img.gdocker.com/docker/sensu_logo_large-c92d73db.png', attachments: [{ text: [slack_message_prefix, notice].compact.join(' '), color: color }] }.tap do |payload| payload[:channel] = slack_channel if slack_channel payload[:username] = slack_bot_name if slack_bot_name payload[:attachments][0][:mrkdwn_in] = %w(text) if markdown_enabled end end def color color = { 0 => '#36a64f', 1 => '#FFCC00', 2 => '#FF0000', 3 => '#6600CC' } color.fetch(check_status.to_i) end def check_status @event['check']['status'] end end
然后像这样传递一个configuration文件到它
{ "handlers": { "slack": { "command": "/etc/sensu/handlers/slack.rb", "type": "pipe", "filters": [ ], "severities": [ "ok", "critical" ] } } }
这也将包括该处理程序将处理哪些严重性
