Upsilon 介绍
Upsilon 是一个分布式、灵活和可扩展的系统监控程序。
Being distributed means you run service checks on Upsilon nodes in your
network where it makes sense, either on every server or on a management
network, inside or outside the firewall. You can run checks on secure, hard to
reach networks, and push those results to a central server. You can optionally
execute “agentless” checks just by using SSH. Being flexible means that if you
can script it, you can monitor it. Unlike most monitoring systems, the
monitoring scripts are external to the main server, so you can use Upsilon to
execute your monitoring scripts in an extremely robust way. Upsilon has been
used to monitor many different things and is API-compatible with all nagios
monitoring scripts. Being extensible means you can add monitoring checks to
Upsilon at runtime without needing to restart the server. The upsilon-node and
upsilon-web projects both have their own REST APIs.
