Imagine some users complaining that querying PostgreSQL is slow (this never happened right?), and we have to troubleshoot this problem. It could be one of two things: I would normally first check on the environment, specifically PostgreSQL metrics over time. Such monitoring shows if the CPU is too high or how many disk reads were buffer reads. PostgreSQL logs also give information about the environment, such as how many statements were run and if any errors occurred.

Open-sourcing a code base for the world to see after working on it for a long time is a great experience. You should care about what your users want. You want your users to have a great experience using your product. Everything has to fall into place. Performance, responsiveness, user experience, etc. all have to be exceptional. That’s why I think front-end performance metrics are crucial.

Making sense out of logs is not an easy task. Log management solutions, such as Sematext Cloud, gather and accept data from multiple sources. Those sources can have different log events structures, providing a different granularity. They may not follow common, logging good practices and be hard to get some meaning from. Because of that, it is important that the application we develop and follow best practices. One of those is keeping meaningful log levels.

What do you think of a website that displays SSL/TLS certificate errors when you visit it? Most people abandon it in disappointment. A certain amount of trust and respect for the service is lost. After investing a lot of effort and time in getting users to visit your site, and the user finds the site down or showing a warning, it will result in having dissatisfied users. Moreover, if the downtime or warning is due to a security issue, it will also hurt your brand image.

Do you use an error tracking tool for your website? Have you ever tried to debug a problem that a user reported, and when you looked at your error tracking tool the reported error was simply: “Script Error”? Such errors are impossible to further debug because there is no additional information apart from that message.

A user looking for “awesome smartphone 2018” is likely really after “+review:awesome +category:smartphone +release_date:2018”. A clever use of (e)dismax might get us pretty close to where we want, but it’s not real query understanding. There are other ways, of course, like training a model that will, based on the keyword, guess which field it’s looking into.

Your software stack likely consists of web servers, search engines, queues, databases, etc. Each part of your stack emits its own metrics and logs. Depending on the size of your team and structure, different team members might have permissions to look at one set of data, but not the other. Some data is needed for troubleshooting and can be discarded after just a few days, while more important data might need to be kept for months for legal or capacity planning purposes.
