I did work in integrating alert system to pagerduty, hence these are the few positive pointers, I noted.
a. PagerDuty has a real time alerting system.
b. Intimation over phone as message and phone call.
c. Simple interface, yet robust feature. Review collected by and hosted on G2.com.
I did not see any major negatives with PagerDuty, however the cost compare to other compitetors is at the higher number. Review collected by and hosted on G2.com.
