It continuously monitors a service container, triggers alerts when the service goes down, and automatically restarts the service via Ansible playbooks. \u2699\ufe0f Architecture Blackbox Exporter \u2192 Prometheus \u2192 Alertmanager \u2192 Monitor (amtool + jq) \u2192 Ansible Runner\u2026 Read More »<\/a><\/span><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[25],"tags":[],"class_list":["post-293","post","type-post","status-publish","format-standard","hentry","category-miscellaneous"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/posts\/293","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/comments?post=293"}],"version-history":[{"count":1,"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/posts\/293\/revisions"}],"predecessor-version":[{"id":295,"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/posts\/293\/revisions\/295"}],"wp:attachment":[{"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/media?parent=293"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/categories?post=293"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/myallcodes.in\/index.php\/wp-json\/wp\/v2\/tags?post=293"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/myallcodes.in\/wp-content\/uploads\/2025\/09\/image-1.png\")
