Does it alert before a TLS certificate expires?
Yes. Certificate checks alert when the certificate expires in fewer than a configurable number of days.
Middle Monitor runs HTTP, ping, SQL, certificate and SNMP checks with incident alerting — in the same platform that holds the traces and logs explaining the failure.
Pingdom, UptimeRobot and Better Stack are simple, focused and quick to set up, often with more global probe locations than a general observability platform offers. If you only want external uptime checks, a specialist is a reasonable choice.
HTTP and HTTPS with expected keyword matching and latency thresholds, ICMP ping with latency alerting, SQL connection checks, SSL certificate expiry warnings ahead of the deadline, and SNMP.
When a check fails, the incident is correlated with host metrics and application errors from the same window, so the notification can name a likely cause instead of only reporting that something is down.
Status badges and alerts only change after N consecutive bad results, which keeps a single transient timeout from generating a page. Certificate expiry alerts fire immediately.
Slack, email, Jira Service Management, WhatsApp and SMS, or a JSON webhook to your own API. Channels are toggled from the interface.
Yes. Certificate checks alert when the certificate expires in fewer than a configurable number of days.
Checks are executed periodically by the Middle Monitor backend workers, so no agent is required on the machine or endpoint being checked.
