Seeing 90% memory usage and starting to panic? Hold on — MongoDB is designed to use up every bit of memory it can get its hands on. This post is about telling "normal" apart from "actually a problem," and exactly where to start looking once memory really is running out.
A competent monitoring system tells you "CPU is high." A competent diagnostic system also tells you why it's high and what to do about it. This post breaks down the logic behind WAP's diagnostic analysis — from cross-referencing multiple signals, to ranking root causes, to handing you a recommendation you can act on immediately.
How does a replica set stay consistent, and how does a backup restore to any exact point in time? Both answers point to the oplog — the often-overlooked log that holds up the entire high-availability story.
A good monitoring page should tell you what's wrong within ten seconds and why within a minute. This post breaks down what WAP's real-time monitoring page does — overview, drill-down, comparison, and history.
If you're still storing metrics, sensor readings, or market ticks one document per data point in a regular collection, you're paying for storage and query costs you don't need to. Here's how Time Series Collections fix that.
"Health Score: 98" is the output of dozens of metrics, continuously collected and weighted. This post lays out exactly what WAP tracks — from the host, to the instance, to the replication chain, to the query layer.
Every metric on your cluster is a vital sign. Whaleal Platform tracks them continuously, and the moment one crosses the safe line, the alert reaches the right person immediately.
"Just add an index" sounds simple. But how you build it, how you order the fields, and whether it satisfies a covered query decide whether your query runs in milliseconds or just gets lucky.
Whaleal Platform's backup module turns your database into a continuous, recorded timeline — whether it's a replica set or a sharded cluster, any single time slice can be pulled out with precision.
This post walks through MongoDB's two clustering topologies — replica sets and sharded clusters — what problem each one solves, and how to choose between them.
From missing indexes to lopsided shards, from election storms to backups that quietly stopped working — six traps we've seen play out across MongoDB clusters, and how Whaleal Platform turns each into a routine, manageable event.
Whaleal Platform (WAP) is our in-house automation and monitoring platform for MongoDB — visual monitoring, intelligent diagnostics, one-click operations, and point-in-time recovery, backed by enterprise-grade SLAs.
