Most monitoring tools only reach public-facing services. CuliPulse can run an agent inside your network and watch every port that listens there — databases, message brokers, internal APIs, game servers — with no need to poke holes in your firewall or expose anything to the internet. Plus first-class UDP: send a payload, match the reply, done.
A TCP check that only confirms the port accepts a connection misses half the picture. With banner checks you send a real payload and assert on the reply — so you know the service is not just listening but actually healthy and talking the right protocol.
Pick a service and the right port, payload and expected reply are filled in for you. You can tweak anything — or leave it as-is and start monitoring in seconds.
Confirm the port accepts connections, and optionally send a string and assert the response. Works for any TCP service — databases, brokers, proxies, SMTP servers.
Check that any TCP port is open and accepting connections — PostgreSQL, MySQL, MongoDB, Redis, RDP, message brokers. From CuliPulse's network for public hosts, or from an agent on your network for internal ones.
Not in the preset list? Write your own send string and expected response — plain text or hex-encoded bytes for binary protocols.
UDP has no handshake, so most monitoring tools skip it. CuliPulse's agent does the work: it sends your payload, waits for a reply, and checks what came back. Internal DNS resolvers, NTP servers, and game backends are all fair game — even the ones that never touch the public internet.
Craft a payload, fire it at the UDP port, and assert the response — exact match, contains, or a regular expression. If nothing comes back in time, it's down.
UDP monitors always run through an agent. That's not a limitation — it's the only way to reach a private DNS server or an NTP daemon that isn't exposed to the public internet. Drop an agent on the same network and you can watch anything.
Add more than one checkpoint — a mix of CuliPulse's network and agents on your own infrastructure — and we wait for several of them to agree before calling something down. A momentary glitch on one path won't wake you up at 3am.
Add a TCP or UDP monitor, pick a preset or write your own banner check, and get alerts you can trust — even for services that never touch the public internet.
