I recently had to setup a few monitoring dashboards in Grafana based on a Prometheus data source. I focussed on a couple of already existing counter metrics. I assumed that those are the simplest metrics available and it should be easy to extract some meaningful numbers and graphs out of them. It turned out that I had underestimated the complexity of Prometheus Counters. It took me quite some time to understand what I have to do to get the numbers and graphs that I wanted. In this article, I want you to join me on my way to understand how Counters in Prometheus work and how to query them to get the right information.

To better understand the results of our upcoming queries, it’s a good idea to have a little playground where we can create and increase a counter in a simple and controlled way. As an easy option we can create a simple spring-boot application and use the Micrometer Prometheus plugin to write our counter. You will find lots of resources on the internet describing how to set up a spring-boot app. To use the Micrometer Prometheus plugin we just need to add the appropriate dependency to our project. If we use Maven, we have to add the following lines to our pom.xml file.

To run Prometheus we can use the official Docker image. As we need to extend the configuration, we create a custom Docker image based on the official one and add our own configuration file.

Prometheus collects metrics from monitored targets by regularly requesting appropriate HTTP endpoints on these targets (called scraping). To register our spring-boot app (running on the host machine) as a new target, we add another scrape job to the default prometheus.yml.

We can verify this by looking at the targets status page (at http://localhost:9090/targets). It should display two targets, Prometheus itself and our spring-boot app, both with state UP. Using the graph section (at http://localhost:9090/graph), we should also be able to query some default metrics created by spring, e.g. jvm_memory_used_bytes.

The Micrometer registry converts this into a Counter metric named orders_created_total. _total is the conventional postfix for counters in Prometheus.

After restarting the sample app, we can open the graph page of the Prometheus web UI again to query our metric. Prometheus provides a query language called PromQL to do this. To query our Counter, we can just enter its name into the expression input field and execute the query. We get one result with the value 0 (ignore the attributes in the curly brackets for the moment, we will get to this later).

Prometheus scraps its targets on a regular basis. As we did not specify an interval in the scrape job, Prometheus uses the default interval to scrape our sample app. This means that the current value of our counter is requested and updated every 10 seconds. When scraping a target, Prometheus reads the current values of all provided metrics and adds them as new instant values to the appropriate instant vectors in its database (the time series database). So, according to the database, the instant vector of our counter actually did not increase by 1 every 5 seconds, but by 2 every 10 seconds.

When we execute our query, chances are high that we do this somewhere in between two scrapes. Let’s say Prometheus scrapes our sample app every 10 seconds starting at 10:30:00 getting the following counter values

We don’t get the value from 10:30:20, because that was more than 5 minutes ago. Because of that, if we calculate the increase within this range vector, the result is 58 (76 - 18). Now, that’s not what Prometheus returns. The reason is (again according to the documentation) that the increase function tries to extrapolate missing values and estimate the values at the borders of the range. As you can see above, the result Prometheus returns is more exact than the one that we came up with, but it’s still not the right value (we know because of the controlled environment we set up).

Lesson learned: Don’t expect exact values from Prometheus. It’s not designed to give you the exact number of anything, but rather an overview of what’s happening.

It looks a little strange at first glance, because the values seem to jump up and down. But if we look at the labels on the Y axis, we see that this is because Prometheus shortens the scale so that the whole graph is visible as detailed as possible. In our case it means that it only shows the area around the 12 orders/minute, because all values are within this area. If we increase the graph range to one hour, Prometheus zooms out to show how the rate increased from 0 (before we started increasing the counter) to 12. The resulting graph matches our expectations.

The first thing that comes into our minds might be to create separate counters for those different types of orders, e.g. de_orders_created_total, at_orders_created_total, and so on. This would lead to registering counters for every possible combination of attributes that we might want to query. We would also have to ensure within our shop, where those counters are written, that for every created order all the appropriate counters are increased. Fortunately, Micrometer/Prometheus provides a better way to handle this.

We can add some tags (as they are called in Micrometer) or labels (the same concept in Prometheus) to our counter and set the appropriate attribute values every time we increase it. To keep the implementation of our sample app as simple as possible, but have some variation within our values, let’s use separate scheduler jobs (with different delays) for two different countries and choose the payment and shipping methods randomly.

If we query our orders_created_total metric after restarting our sample app, we no longer see only one result but many. Within the curly brackets we ignored so far, we can see the keys and values of our three labels (the other two labels job and instance are automatically added by Prometheus when scraping the values from the several targets).

The reason why we see those multiple results is that for every metric (e.g. Counter) Prometheus creates a separate value vector (called time series) for every combination of label values. So, instead of simply getting an instant vector containing the values, what we really get when we query our simple metric is an instant vector containing one or many time series – each containing a vector of values for that particular counter and label values at the different instants. We can see the different time series more clearly when we switch to the graph again.

Due to the fact that Prometheus creates separate time series for each combination of label values, only labels with a small number of possible values should be used. Using an order number, which is different for every order that is created, as a label is clearly a bad idea. It would result in one time series per order where the value is set to 1 and will never increase. Often, enumerations within our domain model are good candidates for labels.

But how do we get the overall number of orders? We clearly don’t want to query all the separate values to sum them up on our own. Well, Prometheus will do this for us if we use the sum aggregation operator (see documentation).

This query returns the overall number of orders created within the last 5 minutes, ignoring all the different label values. We can combine sum with some label expressions, e.g. to get the number of all DE orders. A better option might be to tell Prometheus to respect selected labels when aggregating, e.g. calculate the sums by country.

As the result of this query we get two records, one for each country label value. All other labels are ignored and removed from the result set. In analytics systems that are based on Prometheus (e.g. Grafana), this type of query can be used to generate pie charts or repeating (parameterized) components (e.g. single value graphs that are rendered for each available country label value and show the number of orders for that country).

We saw that a Counter, which looks really simple at first glance, can turn out to be more complex than expected. Prometheus provides some other types of metrics. One of them is the gauge. According to the documentation it represents a single numerical value that can arbitrarily go up and down. So, like a counter, a gauge also represents a single value, but instead of only increasing, it can also decrease. That sounds even more complex, doesn’t it?

Science fiction has always served as a window into a potential future, namely in the way of technology. But what was once regulated to episodes of Star Trek is quickly becoming the stuff of reality. Many fixtures of these kinds of shows and books have begun to inspire real-life counterparts, including - but not limited to - touchscreen technology.

One only has to look at how far cell phones have come since their inception. Physical keyboards, like those from BlackBerry, gave people about as much of a solution as is possible for those who found themselves doing more on the devices as they became more advanced. Where tactile options came up short, touchscreens graciously stepped up to bat, providing a much fuller experience. This kind of functionality then spread to tablets, which are considered by many to be rivals of laptops and even standard PCs.

While there are still some things that are best done on a desktop computer, that does not change the fact that many users find themselves longing for the same abilities on their PCs afforded by many of their mobile devices. This is what helped breed the touchscreen monitor market, which has many viable options for people seeking the best of both worlds. With stronger computing power and a finer ability to control actions occurring in the screen, users can get more work done in new and exciting ways.

Traditionally, computer mice are what have allowed us to "touch" in a virtual context, but touchscreen monitors are changing all that. It might be said that the reason that mice were used in the first place was because the technology had not evolved to a responsive enough level to enable that natural solution. Now that people have the touchscreen technology, they want it everywhere.

If one thing is for certain, it is that the burgeoning adoption of touchscreen technology is no fad. Proliferation has already come too far to turn back now, and computer manufacturers are taking notice. Everyone is trying to get a piece of the action, including ELO Touch Solutions, Laiputuo Electronics, Planar, HP, 3M, Touch Systems, ViewSonic, Dell and ACER as well. Getting into the touchscreen monitor game is a no-brainer for the companies involved in this generation of computing. With so many different applications made for touchscreen monitors, options exist for all sorts of interested parties.

Touchscreen monitors are becoming the new standard in both private and enterprise settings. Here are some of the ways they can be leveraged effectively for business: touchscreen monitors for workstations, touchscreen monitors for hospitals, and touchscreen monitors for POS systems.

Another point of deep interest for me is religion, myth, and spirituality. And the myths and legends of ancient Greece and Rome have always fascinated me. However, I’ve never been able to get into the ancient poetic sources because my modern brain just doesn’t process them right. That all changed when I discovered that English comedian Stephen Fry had penned a reimagining of the classic gods, including Zeus, Pandora, Prometheus, and more. I downloaded it immediately.

I don’t often read fiction and almost never write it (except for screenplays for my films). But I love reading about writing as I continually seek to improve my professional craft. So, Consider This by Chuck Palahniuk was only a half-fit for me when I first picked it up. I figured that the author of Fight Club would have some meaningful tips on writing, even if I don’t write prose fiction.
