Creating Watchers
Follow these steps to create a watcher in the Control panel:
- Go to the Monitoring section.

- Interval — how often the service will be checked;
- Timeout — how much time before a check is considered unsuccessful;
- Check sequence — what order checks will be performed in from the selected points of presence (sequentially, simultaneously, or randomly);
- Host/IP — the domain name or IP address of the server to be checked;
- Protocol — the preferred protocol the check should be performed over (IPv4 or IPv6).
- Specify the additional parameters. Individual parameters are set for each watcher:

| 6. Select the points of presence where the watcher will be launched from. | |
