Pingdom provides monitoring service for websites. As of now they are offering free (limited features) and paid monitoring service.
On January 28, 2016, they will discontinue their existing free plan. They will continue offering free monitoring but it will have very limited features.
The following features will be removed from their free plan:
- Public Status Page
- Multi-User Login
- IPv6
- SMTP, POP3, IMAP
- TCP, Ping, DNS, UDP
- HTTP Custom Checks
- BeepManager
- Report Banners
- Multiple email reports
- API Access
- Root cause analysis
- Transaction Check (Not Included)
- Real User Monitoring (Not Included)
In fact you can say that they will be removing almost all features from free plan. In free plan, you will be able to monitor only “HTTP(S) Check” at 5 minutes interval that’s it.
