Are you servers and websites online? Are they slow or unreliable?
Server Ranger 2 does the monitoring for you and sends you alerts with email, SMS(*) text messages or notifications when things aren't right.

Monitor the performance and uptime for any device, server or website. Server Ranger 2 can use Ping for basic monitoring or more advanced testing for websites and email servers. Discover weak spots in your infrastructure.

Nodes performing properly are in green. Yellow indicates the node is online but slow. Red is for offline. Only interested in 1 device? Switch to Single Server Mode to reduce on-screen clutter.

Server Ranger 2 allows you to decide exactly what policy each server should get. Use an Alert Policy such as Critical, Normal or Unimportant on any server. Or give each server its own custom policy.

Here's an example policy for a website. "Send me a notification and an email when my website goes offline for 10 minutes, and only send one alert."
Here's a policy for your company's database server. "If the server's latency is greater than 1000ms for 10 minutes, or if it's offline for 5 minutes, send an email alert to me and send both an email and an SMS alert to my IT sysadmin. Repeat the alert a maximum of 3 times."

Alerts can include emails with multiple recipients, SMS text messages to anywhere in the world with multiple recipients, on-screen alerts, notifications, sounds and dock icon badge.
Is a server not important? Just switch its alerts off. Server Ranger 2 can continue to monitor the server, logging its performance and uptime.

New in Server Ranger 2, eliminate false positives with the Anchor Server feature. Simply choose any server or website that you can rely on, such as a Google DNS server, and Server Ranger 2 will verify the local computer’s connection with it, before issuing any alerts.

Server Ranger logs every response from your devices. Spot patterns of poor performance and print or export the evidence to a CSV file.

Server Ranger 2 has a second window, ideal for a full-screen view, or for a screen on the wall.

Server Ranger 2 can scale from monitoring one simple website to any number of servers and devices.

Perfect For My Needs

Monitoring a bunch of VPS, shared hosting accounts, and local servers is so much easier with Server Ranger. I used to use free online services which always seemed to require multiple accounts for multiple sites, but I just run Server Ranger on my Mac now and reduce the hassle. The app is great. Seriously. If you have servers to monitor, you need this.

The cats meow

Simple and quick to set up, yet a very powerful motoring tool. The alert feature is was what I was looking for and it did not disappoint. After all my research, I do not think you can do better for the price.

Excellent Network Tool

I’ve looked at some sophisticated network tools to help me watch my office array of computers and several remote networks. This is by far the easiest to set up and teach my staff how to use when trying to figure out where the network failure is. We can monitor our Filemaker server, several macOS Servers, Airport routers, and Gateway routers amonth three locations. It is well worth the price to me.
