We offer a free plan with support for 5 monitors. Each monitor can be configured with a minimum polling frequency of 5 minutes.
The IP addresses we perform checks from are listed here. Please make sure you whitelist these IPs in your Firewall configuration.
Pinger Man sends HTTP requests to your web server. These are typically visible in the web server logs such as apache.
For each monitor you must specify the contacts that need to be alerted for up/down status changes. Please make sure you have selected contacts in the Alerts tab of your monitors.
SMS alerts can only be sent if you have enough SMS credits. You will need to purchase a subscription to receive SMS credits.
