Introduction
SmokePing is a network latency tracking tool. Tracking your server’s network latency can give you a useful picture of the overall health and availability of your server. For example, it can help you determine if your network is overloaded or alert you to packet loss, which may indicate an incorrect router configuration or downed device.

SpokePing’s creator, Tobias Oetiker, also created a data logging and time series graphing utility called RDDtool. SmokePing uses RDDtool, so you have access to its sophisticated graphing capabilities too.
This tutorial will show you how to install and configure SmokePing with Apache on FreeBSD.
Prerequisites
To follow this tutorial, you will need:
- One FreeBSD 11 server with a root user. On DigitalOcean, the default freebsd user is fine.
A FreeBSD Droplet requires an SSH key for remote access. For help on setting up an SSH key, read How To Configure SSH Key-Based Authentication on a FreeBSD Server. To learn more about logging into your FreeBSD Droplet and basic management, check out the Getting Started with FreeBSD tutorial series.
Step 1 — Installing Apache with FastCGI Support
To begin, we’ll install the Apache web server and its FastCGI module, which SmokePing uses to power its web interface.
Final fantasy xv a new empire multiple accounts. First, update your server’s repository information.
To install Apache with FastCGI support, you can just tell
pkg
to install the FastCGI module. pkg
will handle all dependencies needed by the module itself, so it will automatically install the main Apache package as well.Confirm the installation by pressing
Y
. Once Apache is installed, we’ll need to customize it to get it working.Step 2 — Configuring Apache
There are two small changes we’ll need to make to Apache: updating some server information in
httpd.conf
and enabling the FastCGI module.First, open
/usr/local/etc/apache24/httpd.conf
for editing.Edit the two directives below. Set
ServerAdmin
to your email address, and uncomment (by deleting the preceeding #
) and edit ServerName
to your server’s IP address.Save and close the file.
FastCGI is not a default module, so we have to add it to Apache’s configuration to load it. To load the module, we’ll need to create a new configuration file in
/usr/local/etc/apache24/modules.d/
and add the module information.The module README, found in
/usr/local/etc/apache24/modules.d/README_modules.d
, says “files are automatically included if the name begins with a three digit number followed by _
and ending in .conf
”. To comply with this, we’ll create a file called 001_fcgid.conf
.Paste the following into the file, which tells Apache to load the module and where to find it.
/usr/local/etc/apache24/modules.d/001_fcgid.conf
Save and close the file.
Now that Apache with FastCGI is set up, we can install SmokePing itself.
Step 3 — Installing and Configuring SmokePing
Installing SmokePing is straightforward because it’s in the package repository.
SmokePing’s configuration is in
/usr/local/etc/smokeping/config
by default. You’ll need to edit this file to customize a few fields.You’ll need to edit four fields in the ***General*** section:
owner
, which should have your namecontact
, which should have your email addressimgurl
, which should be updated to use your server’s IP addresscgiurl
, which should also be updated to use your server’s IP address
Here’s what the file will look like when you’re done:
SmokePing has support for a master/slave architecture, to use their terminology. In this tutorial, we’re only setting up SmokePing on one machine. Consequently, comment out the *** Slaves *** section of the configuration by prefacing each line with a
#
./usr/local/etc/smokeping/config
Keep this file open, as we’ll continue editing it in the next step to set up SmokePing’s targets.
Step 4 — Defining Targets
The last thing we’ll add to SmokePing’s configuration file are targets. To paraphrase SmokePing’s explanation, targets are a hierarchical list of hosts which mark the endpoints of the network connections the system should monitor. Every target will specify what kind of probe to use, which integrate an external ping command into SmokePing (like
fping
).In this tutorial, we’ll set up a configuration that monitors the latency between your server and two FreeBSD
pkg
mirrors. We’ll create three graphs: two that shows the latency for each of the two mirror servers independently, and one that shows the latency of both mirror servers at once.Targets are configured In the *** Targets *** section of SmokePing’s configuration file. There are many variables you can use to customize your targets, but here, we’ll just use the following:
- probe: The ping command to use to probe for latency.
- menu: The default menu to show in the GUI.
- title: The title of the corresponding SmokePing page.
- remark: The text that will appear on the page.
- host: The IP address or hostname endpoint.
Ep evaluator 9 keygen software. First, delete the existing sample configuration so the end of your file looks like this:
**Targets** Section on /usr/local/etc/smokeping/config
Then, copy and paste the following configuration under the existing default settings.
**Targets** Section on /usr/local/etc/smokeping/config
Let’s explain what this is doing.
Targets are hierarchical, meaning you can nest levels of targets to help with organization. Each nested level of targets will create a new submenu in the SmokePing GUI showing different graphs.
In our configuration, the
+ targets
line means we’re defining a nested level of targets. Nested targets will inherent the values of their parent configuration, so we don’t need to include the probe = FPing
line again if we want these targets to use the same probe. However, we updated the title
and menu
variables for the new subsection, so the page on the site will have a different title and menu.The
++ pkgmir_xxx
lines mean we’re defining a second nested level which includes two targets. These have a host variable for the address of the endpoint, which are our two FreeBSD pkg
mirror servers.The above configuration will create one graph per target. Below it, add one more section to combine multiple targets into one graph.
**Targets** Section on /usr/local/etc/smokeping/config
Note that this section uses the two targets we already configured (
/targets/pkgmir_nyi
and /targets/pkgmir_ydx
).Finally, save and close the file. SmokePing’s configuration is all set up, so let’s connect Apache and SmokePing and start the respective services.
Step 5 — Connecting and Enabling the Services
Create a configuration file for Apache in
/usr/local/etc/apache24/Includes/
called smokeping.conf
. Here, we’ll add the information Apache needs to handle requests to SmokePing’s web interface. Copy and paste the following into the new file:
This tells Apache where to find SmokePing’s files and makes sure it uses FastCGI.
The default service configuration for Apache and SmokePing will not start the processes at boot. To change that, execute the following two commands.
The output for the aforementioned two commands should look like this:
Now, you can start the Apache service.
If it starts successfully, you will see:
Install Kubectl On Centos 7
If not, you’ll see an error which you can use to debug any issues in the configuration file. Finally, start the SmokePing service.
Everything is running, so let’s see our graphs in action.
Step 6 — Accessing SmokePing’s Web Interface
You can access SmokePing’s web interface by visiting
http://your_server_ip/smokeping
in your favorite browser. You’ll see a page with the title and remark you specified in step 5. If you didn’t change any of the values, it will look like this:You can see your graphs by navigating the menu on the left. Notice the Targets and Multi Targets options in the menu; these are the targets we defined in Step 5.
Click on Targets. You’ll see the first two graphs we defined, one for each mirror server. On the left, you’ll see the nested list of targets, which mirrors our configuration file.
Next, click on Multi Targets. You’ll see the combined graph here.
If you run into trouble, you can check the logs for help in diagnosing the problem. Apache records its logs in two files:
/var/log/httpd-access.log
and /var/log/httpd-error.log
. SmokePing has one log file, which is /var/log/smokeping.log
. Remember that if you change SmokePing’s configuration, you’ll need to reload the daemon with sudo service smokeping reload
.Conclusion
In this tutorial, you set up SmokePing with Apache and created some example probes to test logging and graphing. From here, you can customize your probes and graphs to whatever you’d like to track. SmokePing has a lot of other features, like slaves, alerts, and support for your own mail server. Check out SmokePing’s official documentation for more detail.
