MongoDB is an efficient database storage system that makes it possible for one to access important information with ease. Unlike other common database systems, MongoDB is a document-based system that allows one to query, index and sort information with ease. Its ability to process and display information in an easy to read format enables a business to see how to improve performance in order to boost profitability and better meet customer needs. What is more, MongoDB comes with a number of handy tools that allow a user to monitor performance and improve it in order to access, add or delete information on the program quickly, easily and efficiently. Following are some expert-recommended tools that users will want to check out in order to use MongoDB to its fullest potential.
Mongostat is a particularly useful tool that is included in the MongoDB package. Users can utilize this tool to get a quick real-time overview of the database status. The program offers a view of database operations by type, enabling a company owner, manager or executive to see how many searches, updates, deletions and inserts have occurred within a given time frame.
Mongotop, another important tool, offers a real-time look into a running MongoDB instance. It can provide an IT professional with information regarding how long it takes MongoDB to read and write data. This information is important when creating an index strategy and/or deciding on how to shard the database in order to increase efficiency.
The Mongo serverStatus command makes it possible for a user to see the database’s current state and collect statistics based on it. The dbStats command provides storage statistics for a particular database and includes information pertaining to the amount of storage space used, the quantity of data in a particular database and index counters. CollStats, another handy feature, is handy for seeing the size and amount of data included in any given collection. It also provides index-related information.
Third Party Tools
There are also a number of external, third party tools that one can use to accurately analyze MongoDB performance. Most of these tools, like MongoDB, are open source, which means that they can be used with ease on any type of system; what is more, many are frequently updated as users can provide information in real-time to developers who are then able to improve tools to ensure they operate at peak performance. Even so, users are responsible to install, configure and maintain the tools on their own servers as they are not part of the MongoDB.
Munin is used to retrieve server statistics using the mongo-munin plugin. The program can also retrieve collection statistics and collection count for a single database with the mongomon plugin. Additionally, there is a Munin plugin for Ubuntu which contains other munin plugins which are not available in the main distribution system.
Nagios, another helpful plugin, is a simple check script program written in Python.
Dex analyzes indexes and queries, comparing MongoDB log files and indexes to help users see how to best modify the program’s index system in order to improve speed and efficiency.
Hosted SaaS Monitoring Tools
There are also a number of Hosted SaaS monitoring tools that a user can take advantage of, including MongoDB Cloud Manager, VividCortex, Scout, SPM Performance Monitoring, Application Performance Management, and Datadog.
MongoDB Performance Signals
Just as important as knowing which tools to use to monitor MongoDB performance is knowing which signals to look for when going over search results. ObjectRocket experts recommend looking at replication lag, replica state, locking state, disk utilization, memory usage and number of connections.
Replication lag shows if there is a delay in copying data from one node to another and can be useful for those who want to access system speed and efficiency. It may indicate that it’s time to delete old indexes and/or create new ones. It may also show if sharding the database is in order to speed up search time and reduce the amount of time it takes to add new information into a relevant database. Checking replica state enables a user to make sure secondary nodes are working as they should. The locking state shows not only what data locks are set but also the length of time they have been in place. This metric may indicate serious problems such as a badly configured index or hardware failure. It may also indicate that a particular document or set of documents is being regularly accessed by numerous employees and/or business partners or clients at the same time. Disk utilization and memory usage monitoring enable a resident IT expert to assess how much memory and RAM space is being used by MongoDB users at any given time. Additionally, knowing the number of connections available will help users map out a MongoDB data storage plan that will make it possible for users to search, access and even modify information as needed without undue delay.
MongoDB is a versatile database with much to offer. Its versatile options enable users to configure the program to suit their exact needs; given this fact, it is not surprising that MongoDB has been used by companies of various sizes and in various industries, including financial institutions, government agencies, social media platforms, e-commerce platforms and gaming companies. Furthermore, the fact that MongoDB is an open source program allows users easy access to all that it has to offer and enables experts to analyze the program with ease and offer advice that can save companies and individuals a great deal of time and hassle.
