Watchdog Server Monitoring

Watchdog Server MonitoringWatchdog Server Monitoring

The Modern Alternative to Prometheus

Replace Your Slow Prometheus Configuration With Watchdog’s Zero-Config, Automatic Alerts

Watchdog is the predictive system-level vitals monitor that sends you and your team Essential Alerts™ that proactively notify you of all the hardware issues you need to know about.

“Prometheus also does not offer ... anomaly detection.”

–Dr. Frederick Ryckbosch, Department of Applied Mathematics, Computer Science and Statistics, University of Ghent, Belgium

Can You Replace Prometheus with Watchdog?

Watchdog includes Essential Alerts™ out of the box and takes less than a minute to install, while Prometheus can’t even offer anomaly detection. See how Watchdog stacks up.

Setting up Watchdog on existing large installations is easy because there is no config required to get Essential Alerts on even hundreds of servers.

Install & Config: How Does Prometheus Compare to Watchdog?

With Prometheus, you’ve got to download plugins and spend all day configuring them. If you’ve got an older Prometheus install, you might even have to pay up to $18,500 to have trained technicians fly out to upgrade your database in order to avoid historical data loss.

Prometheus: Deploys in 15+ Steps

Prometheus: Deploys in 15+ Steps

Part 1: Installing Prometheus Daemons

STEP 1: Download the source archive

(1 command) $ tar -zxvf Prometheus-3.4.0.tar.gz

STEP 2: Create user account

(2 commands) groupadd Prometheus useradd -g Prometheus Prometheus

STEP 3: Create Prometheus database

STEP 4: Configure the Sources

(1 command) ./configure --help ./configure --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-libxml2 ./configure --enable-server --with-postgresql --with-net-snmp ./configure --prefix=/usr --enable-proxy --with-net-snmp --with-sqlite3 --with-ssh2 ./configure --enable-agent

STEP 5: Make and install everything

(2 commands) $ make dbschema $ make install

STEP 6: Review and edit configuration files

  • edit the Prometheus agent configuration file /usr/local/etc/Prometheus_agentd.conf
  • edit the Prometheus server configuration file /usr/local/etc/Prometheus_server.conf
  • if you have installed a Prometheus proxy, edit the proxy configuration file /usr/local/etc/Prometheus_proxy.conf

STEP 7: Start up the daemons

(3 commands) shell> Prometheus_server shell> Prometheus_agentd shell> Prometheus_proxy

PART 2: Installing Prometheus web interface

Copying PHP files (4 commands)
  • /usr/local/apache2/htdocs (default directory when installing Apache from source)
  • /srv/www/htdocs (OpenSUSE, SLES)
  • /var/www/html (Fedora, RHEL, CentOS)
  • /var/www (Debian, Ubuntu)
mkdir <htdocs>/Prometheus cd frontends/php cp -a . <htdocs>/Prometheus locale/

Installing the Frontend









Typical Prometheus Fee Structure

As open source software, Prometheus is offered for free once you make it through the installation. Hosted Prometheus is a third-party option. You can skip the painful installation process detailed above, but then you have to budget for your needs

Add on inevitable support contracts, a developer salary to maintain your configuration, and paid courses to learn it, and you can see why Prometheus isn’t really free.

Watchdog Watchdog

Unlike Prometheus, once Watchdog’s daemon is installed and enabled, Watchdog automatically monitors ulimit, filesystems, CPU usage, memory usage, disk I/O, disk space, and long-running processes.

Typical Watchdog Fee Structure

$0 - Free Forever

We aren’t kidding when we say it’s free.

We get the frustration of fighting fires all the time, always balancing the need to fix production, add more monitoring, and do more of the real DevOps work you were hired to do.

Watchdog is free forever because we want to help system admins get ahead of the firefighting curve. Our founders spent years doing on-call DevOps monitoring, day and night.

“I gotta say, Watchdog is pretty cool for a free offering.”

Aaron Mefford –Aaron Mefford, VP of Technology & Development, DMG

Built for Cloud, On-Premise, Distributed, or Monolithic IT Infrastructures

Watchdog Works in Any Architecture & Under Any Scenario

Watchdog runs entirely on your server. In fact, after installing the Blue Matador Smart Agent, your server detects hardware anomalies and generates the report metrics itself. And it does this with the amazingly low overhead that our Smart Agent provides (<2% CPU overhead, <2% memory usage, and 90% gzip compression).
