How frequently does Phare monitor my website?

You can configure Phare to check your website or API as frequently as every 30 seconds. This high-frequency uptime monitoring ensures you're notified almost instantly when downtime occurs.

Can I monitor APIs that require authentication?

Yes, you can configure custom headers for your monitoring requests, allowing you to pass authorization tokens and easily monitor APIs behind authentication layers.

What are success assertions?

Success assertions allow you to define advanced conditions to determine if a check is successful or failed. For example, you can assert that the response body contains specific text or that the response status matches the pattern 2xx.

How do you prevent false positive alerts?

Nobody likes waking up for a one-time network hiccup. Phare allows you to configure confirmation settings to require multiple consecutive failures, or failures from multiple monitoring regions, before an incident is created and alerts are triggered.

Is SSL certificate monitoring included?

Yes, SSL/TLS certificate monitoring is included out of the box. Phare tracks expiration dates automatically and alerts you before they run out, helping you avoid security warnings for your users.

Watch over websites and APIs: From HTTP(s) endpoints to TCP sockets, with custom headers and unique user agent, if it talks, Phare can listen.
Monitor globally: Choose between 11 locations in Europe, America, Asia and Oceania, that run monitoring checks at the edge without proxies.
Set custom headers: Add custom headers to monitoring requests to bypass firewalls or check APIs behind an authentication layer.
Choose the sensibility cursor: Double (or triple) check an incident before sounding the alarms to reduce false positives. Same for recoveries.
Allocate the right resources: Choose your monitoring interval, anywhere from micromanaging every 30s to a more chill hourly check.
Nerd out on the stats: Report on uptime percentages, response times, SLA targets, all sliced by region and tracked for up to 90 days.
Manage certificates: Certificates are automatically discovered and monitored, you can get alerted when they are about to expire, or when a new one is issued.
Stop overthinking: Not sure what settings to choose for your monitor ? Keep the default values and get smart suggestions if anything can be improved.
Decide success conditions: Create sets of advanced conditions to determine when a monitor should be considered as successful or failed.

“Phare is really easy to set up and has been a part of our technological stack for a few years. The product already offers a lot, and is updated frequently with new features.”
