Server Status: It is crucial for a DBA to keep the server running at optimum health to avoid any server outages. Applications Manager provides a clear detail about the server performance, availability, and health in real time. MongoDB Monitoring Tools - ManageEngine Applications Manager

Server Statistics:

  • Monitor MongoDB resource utilization trends to understand resource consumption and plan accordingly. It helps in identifying the database instances that are eating up storage and memory in the name of unnecessary active connections and unattended queries.
  • Study network traffic, trace traffic patterns, and distribute workloads accordingly to avoid slowdowns and ensure optimum performance.
  • Keep an eye out for locks to identify time taking queues. Identify inactive client sessions to reduce wait time and eliminate deadlocks.
  • Trace database operations and stay informed about poorly performing queries with the database operations counter. Get insights into assert stats and errors with Applications Manager.
  • Get a better understanding about your servers by monitoring the indexes, files, objects, and collections in each MongoDB database. Keep track of memory and storage consumption of each element and optimize resources accordingly.
  • Applications Manager's MongoDB monitor offers comprehensive insights about all the key performance metrics along with index stats, latency, and page faults, etc from a single screen. Keep a keen watch on background flush statistics to identify and rectify issues like replication lag in secondary nodes of your MongoDB servers. These statistics also help you understand and improve the performance of disk I/O operations.
    Monitor journaling statistics to optimize journal file size and usage, and eliminate journaling failures and server downtime to ensure smooth activity. Track commits and data consumed during the latest group commit interval to understand loads efficiently. Keep a count on the time taken for each phase of journaling to identify slow transactions and repair them in time.

Replica statistics: Replica sets play a crucial role in MongoDB infrastructure. Monitoring Replica and Shard statistics help admins ensure high availability. In the event of failure or crash, replicas serve as a backup for the rest of the servers. In order to keep the failover system running, admins must monitor replication count and shards in real time. Keeping an eye out for sharding operations ensures smooth back up and replication processes.

Operation details: Keep count of slow queries and queries that encountered write conflicts. Monitor Operation Scan and Order to identify poorly performing queries and resolve them to ensure optimum MongoDB server performance. Ensure high-availability by identifying write conflicts in secondary nodes with Applications Manager.

Cache Details: Monitoring the cache in real time and clearing unnecessary records and files keeps the server memory and storage clean. With proper insights into the statistics and location data about necessary and unnecessary cache, admins will be able to make the right call to free up space. By monitoring the cache details, the admin team can analyze the optimum size for cache and be alerted in case of a threshold breach. This helps DBAs to respond in time and act before it leads to issues like insufficient disk space or resource starvation.

Reduce performance anomalies and critical incidents:

Monitoring the database infrastructure with Applications Manager steers you clear of performance bottlenecks and server slowdowns. It studies historic data and notifies you when the performance patterns of your key attributes deviate from normal before it leads to a critical issue.

Applications Manager's smart alerting system helps you reduce alert noise and speed up fixes. The tool's adaptive thresholds eliminate false alarms and manual errors that arise while updating threshold profiles of growth-dependent KPIs. You can receive alerts based on severity in case of a threshold breach for critical attributes like CPU, memory, connections, deadlocks, queries, shards, etc. This helps you understand the seriousness of incidents and act accordingly.

Automated alert escalation makes it easier for DRIs to prioritize and work on incidents. Triggering corrective actions on a threshold breach helps you reduce MTTR and eliminate manual delay in resolving issues. Configuring the system to alert you across multiple channels like mail, SMS and Slack based on the severity of the alarm helps you improve mean time to respond (MTTR).

Optimize resources effectively

Monitor resource consumption trends with Applications Manager in real time to understand the requirements of the MongoDB servers better. Obtain accurate resource consumption forecasts and stay informed about potential resource starvation. Make well-informed decisions while optimizing resources. Keep your MongoDB architecture secure from incidents like improper resource allocation and unbalanced load distribution with Applications Manager. Apart from monitoring MongoDB servers, Applications Manager extends its monitoring support to multiple database vendors like:

Common questions asked about MongoDB Monitoring

What is MongoDB monitoring?


Monitoring MongoDB is the process of tracking critical database KPIs like nodes, replica sets, memory, storage, replication, sharding, flush details, journaling etc. to understand the performance of the database servers better. This helps admin teams to identify historic trends, point out performance anomalies, and resolve issues before they become incidents with ease. With a strong monitoring strategy and an eye for every corner of the database, they will be able to cater to the expectations of end users well.

How is monitoring MongoDB through a performance monitoring interface better than CLI?


Multiple application deployments leave a long trail of KPIs behind for the DBAs to keep tabs on. The high-availability set-ups accommodate numerous replicas and shards, which require real-time monitoring and prompt alerting in case of a bottleneck. Accommodating high loads leads to resource saturation. Without proper visibility into active processes and workload distribution among primary and secondary nodes, it can lead to critical crashes and server slowdowns. And manually tackling all these challenges is not scalable for an DBA who is accountable for a disparate IT environment. This creates a necessity for a dedicated MongoDB monitoring service for efficient database administration.

How does a MongoDB monitoring tool help DBAs?


An efficient MongoDB monitoring tool helps DBAs monitor MongoDB servers in real time and identifies potential bottlenecks before servers slowdown. It alerts respective DRIs before anomalies become incidents and aids them locate the root cause of issues with the help of code-level analyses. It also provides foresight into future performance trends and resource consumption to keep the admin teams informed about the capacity and resource requirements.

ManageEngine Applications Manager is one of the best MongoDB monitoring tools out in the market, which can help you gain unparalleled visibility into your database servers and optimize all round performance effortlessly.

How can DBAs monitor MongoDB efficiently?


Admins should ensure that their MongoDB monitoring software is flexible and scalable. Native monitoring tools can help, but a serious oversight can result so that important alerts go unnoticed. This can occur when switching interfaces and especially when the IT environment is disparate, directly affecting the overall performance of the IT ecosystem. Only with a capable performance monitoring solution and a strategized execution can the DBAs excel at managing MongoDB servers. Here's a 5-step protocol to sharpen your moves at MongoDB server monitoring:

  • Install Applications Manager with administrator privileges and configure group discovery for your MongoDB servers.
  • Define critical KPIs and sort your MongoDB monitoring interface according to your priority.
  • Set 3-level threshold values for critical attributes and configure responsive actions on threshold breaches.
  • Assign DRIs for incident escalation and schedule timely polls.
  • Obtain performance forecasts and plan capacity and resources accordingly.

How to fix replication lag in MongoDB servers?


Monitor the OpLogs in real time. Ensure that the OpLog size is at optimum. Keep track of the replica writes and replication count from time to time. Clear the dirty cache frequently and trace background flush statistics to understand the read/write operations. Staying up to date about the mentioned metrics will help you identify replication lag, indicate the root cause, and fix it before it affects the whole cluster.
