fix(condition): Partially support numbers with floating point (#434)
* docs: Don't include Pushover in alerting provider examples * fix(condition): Partially support numbers with floating point Fixes #433 Does not add support for decimal numbers, but it converts float64 to int64. The reason why I'm not just using float64 instead of int64 is because float64 does not support all the numbers that int64 supports, which means this would be a breaking change. Instead, this change at least supports the non-decimal part of floating point numbers. This is an improvement over the current implementation, as right now, numbers with decimals are just converted to 0 when compared using a non-equal operator

Gatus is a developer-oriented health dashboard that gives you the ability to monitor your services using HTTP, ICMP, TCP, and even DNS
|
||||
queries as well as evaluate the result of said queries by using a list of conditions on values like the status code,
|
||||
the response time, the certificate expiration, the body and many others. The icing on top is that each of these health
|
||||
checks can be paired with alerting via Slack, PagerDuty, Pushover, Discord, Twilio and more.
