What Alertra is
Alertra is a web-based service for monitoring websites and servers. Checks can run at intervals as short as one minute, and the listed monitoring includes keywords and servers. Alerts can be delivered through email, phone, SMS, XMPP chat, webhooks, Pushover, or PagerDuty. Alertra is a paid product with pricing from $9.95/mo and a 30-day trial; no free plan is listed. Its Custom monitoring plan is listed at $0.20 a month, with a minimum monthly fee of $9.95 and 60-minute monitoring. That plan therefore uses a different interval from the service’s listed one-minute capability. Alertra is made by Alertra, founded in 2000 and headquartered in Stillwater, Oklahoma, United States. The range of notification channels may help teams route monitoring messages to existing communication and incident tools. Buyers should check which plan controls the desired monitoring interval and minimum charge.
