I am using elasticseach heartbeat to monitor all sites. This will give me most of valuable data. Now i want to monitor certificate expiry. I have field call “tls.server.x509.not_after” which contains expiry dates like “2021-09-15T10:25:02.000Z” . I want to set an alert which certificate will get expire in next 45 days.
Thanks a lot @fadjar340. This will really help.
