Either way, regularly checking the logs remains essential. Within this context, certain log messages occasionally begin to appear, yet, unfortunately, there isn’t much literature on some of them; that’s because ..read more

Percona Server for MongoDB currently has several external authentication options, such as LDAP with SASL, LDAP, Kerberos, and AWS IAM. What is amazing is that SASL can authenticate with Pluggable Authentication Modules (PAM) too. This means that you still have additional external authentication options to choose from through PAM libraries.For a quick demonstration of PAM ..read more

Indexes in MongoDB play a crucial role in improving the query performance and increasing the overall database efficiency. Without indexes, MongoDB will perform a collection scan, i.e., it will read all the documents to find if they match the condition specified in the query and cause low response time. Indexes help in navigating directly to ..read more

Before MongoDB 4.4, we had a tool to use to analyze slow queries from the log file called mplotqueries from mtools (thanks, Thomas Rueckstiess, for the tool and the inspiration).Mplotqueries is a great tool that helped analyze slow queries on MongoDB Community, Enterprise, and Percona for MongoDB versions. But when MongoDB 4.4 was released and ..read more
