Ping Monitoring
Know the moment a server stops replying, and how quickly it reaches the rest of the world.
- Pinged every minute, or every 5 on the free plan
- From 7 locations on 4 continents
- Names or IP addresses, IPv4 and IPv6
Trusted by teams at
Every server, and whether it's there
- 1
See every machine at a glance
Which reply and which don't, in one list.
- 2
Know how close each one is
The round trip on every check, so a slowing network shows before it fails.
- 3
Act before anyone notices
An alert when a machine stops replying, and another when it's back.
Checked from around the world
A machine that's reachable from one network can be cut off from another. Mon pings yours from around the world, so a broken route doesn't go unseen.
7 locations, 4 continents
North and South America, Europe and Asia, so an outage in one region doesn't go unseen in another.
Placed for you, or by you
Mon spreads each monitor's checks itself, or you choose the locations it checks from.
Addresses you can allowlist
Every location's IP addresses are published in your account, ready for your firewall.
Reachability, and everything around it
Knowing a machine replies is the start. Mon also shows how quickly, and where the path breaks when it doesn't.
Hear about it first
When a machine stops replying, Mon tells you straight away - and again when it's back - wherever your team will see it.
- By email, in Slack or to your own webhook
- SMS on paid plans
- Alerted only after the failed checks in a row you chose, so a lost packet stays quiet
How far away is it, really
Every ping records the round trip, so you see how quickly each machine answers - and from where it's slow.
- Round trip on every check
- From whichever of the 7 locations you choose
- A slowing network shows before it fails
Find where it breaks
When a machine is slow or unreachable, a trace route monitor - on paid plans - shows the path to it and how long each hop takes.
- Every hop on the way, timed
- See which network the trouble is in
- Proof to take to your host or ISP
Keep your users in the loop
A public status page shows how each of your services is doing, and maintenance windows keep planned work from counting against you.
- Status pages for the monitors you choose
- Maintenance windows for planned downtime
- A weekly report covering every monitor
Add a hundred in one go
Paste a list of names or IP addresses - one per line, or straight from a spreadsheet - and get a monitor for each, all with the same checks and alerts.
- Names and IP addresses alike
- Machines you already watch are skipped
- URLs are read down to their host
Works with the tools you already use
On Enterprise plans, connect your registrar or DNS host once and Mon imports every domain it finds, picking up new ones as you buy them. On every plan, hear about them where your team already talks.
Namecheap
Every domain registered in your Namecheap account.
Amazon Route 53
Every hosted zone in your AWS account.
Azure DNS
Every DNS zone in your Azure subscription.
Slack
Reminders and alerts posted to the channel of your choice.
Everything else your site depends on
The same account, the same alerts and the same dashboard, for every other check your site needs.

Frequently asked questions
Everything about keeping an eye on your servers with ping.
What is ping monitoring?
It is a service that pings your machines on a schedule - sends each an ICMP echo request and waits for the reply - and tells you as soon as one stops replying. It's the simplest way to know a server, router or any other device on the internet is still there.
Is ping monitoring free?
Yes. Mon's free plan includes 5 monitors pinged every 5 minutes, and each machine you watch uses one. Paid plans start at 10 monitors and ping as often as every minute.
How does Mon ping my machines?
Each check sends an echo request to the machine from the locations Mon places it at, and records how long the reply took to come back. You choose how many failed checks in a row it takes before you're alerted, so one lost packet doesn't wake anyone.
My server doesn't answer pings. Can I still monitor it?
Many firewalls drop pings on purpose. Allow ICMP from Mon's published addresses, or watch the server another way: a port monitor checks the service you care about accepts connections, and a website monitor checks a site answers properly.
How is ping different from port or website monitoring?
A ping tells you the machine is reachable. A port check tells you a service on it is accepting connections, and a website check tells you the site answers properly. A machine can reply to pings while its database or website is down, so watch what matters most.
Can Mon show me where the connection breaks?
Yes, on paid plans. A trace route monitor follows the path to a machine and times every hop on the way, so when it's slow or unreachable you can see which network the trouble is in.
Where are the pings sent from?
From 7 locations: Virginia, New York, Dallas, California, São Paulo, Frankfurt and Singapore. Mon places each monitor's checks for you, or you can choose the locations yourself.
Can I monitor IP addresses as well as names?
Yes. Give a monitor a name or an IPv4 or IPv6 address - a router, a server without a domain, or anything else that should answer.
Can I add all my machines at once?
Yes. Paste a list of names or IP addresses - one per line, or straight from a spreadsheet - and Mon adds a monitor for each, skipping any you already watch.
