HPulse.com service features are described below.
Test types
- Domain Names related tests:
- DNS - hostname to IP-address resolving
Performing a DNS lookup for hostname. If no IP will be resolved for hostname, the alert notification procedure is initiated.
We log a DNS server response time for this kind of test.
Use this test to know if your DNS server works and correctly resolves domain names.
- MX - MX-servers monitoring
Performing a DNS lookup for first 3 MX-servers of a specified domain name and execute SMTP test according their MX priority. In case of no one SMTP server gives us correct response code (2xx) at 25 port, the alert notification procedure is initiated.
We log a time for establish TCP connection and server response time over established connection.
Use this test to know if your MX-servers works correctly.
- Servers and Services availability related tests:
- PING - monitoring of the server availability using ICMP echo request/reply
ICMP packets (10pts with interval 1 second) are sent to the host specified according to RFC 792 and calculates average round-trip time. Note that many firewalls are configured to reject or ignore ICMP packets. If our ICMP feature will not work for you due to your firewall configuration, consider specifically allowing our monitoring servers access to ICMP by «whitelisting» our IP addresses. A list of our IP addresses can be given by e-mail request.
We log an average server ping RTT time for this kind of test.
Use this test to know if your server works at all and is available from internet.
- HTTP - Web servers and sites monitoring
The specified URL is requested via the HTTP HEAD method to ensure an HTTP 2xx response code is received. This is a basic HTTP protocol check ONLY, the URL content IS NOT loaded. After receiving HTTP HEAD method server must generate a page but do not send a content to client, only headers. If specified over-SSL connection, our service will establish an SSL connection with a server before a test will executed. Our service uses own user-agent fields.
Before a test executing the ICMP echo-request packet will be sent to a server and RTT time will be logged to give you more info to compare logged times.
The following HTTP(S) features ARE NOT supported by HTTP test: content verification, basic authentication, page change detection, HTTP POST.
We log a server ping RTT time, a time elapsed to establish TCP connection and time for getting a request from the server over established connection.
Use this test to know if your site works correctly and as fast as you want.
- HTTP-Content - Web sites content change monitoring
The specified URL is requested via the HTTP HEAD/GET/POST method to ensure an HTTP 2xx response code is received.
This test supports HTTP Basic authentification and content verification by checksum calculation and keywords searching. You may give us a text strings of a begin/end of text areas to analyze to avoid checksum modification warning of a current time changing on your page.
On checksum modification a warning notification procedure is initiated.
If keywords searching fails an alert notification procedure is initiated.
If specified over-SSL connection, our service will establish an SSL connection with a server before a test will executed. Our service uses own user-agent fields.
Before a test executing the ICMP echo-request packet will be sent to a server and RTT time will be logged to give you more info to compare logged times.
