JusDB vs MyDBops

Audits binary log volume consumption and inspects replica lag metrics to prevent CDC stream interruption and disk exhaustion.

# 1. Audit active binary log count and storage volume consumption
mysql -h db-primary -u dbre_admin -p -e "
SHOW BINARY LOGS;
SELECT 
  ROUND(SUM(file_size) / 1024 / 1024 / 1024, 2) AS total_binlog_gb 
FROM performance_schema.binary_log_status;"

# 2. Inspect replica lag and semi-synchronous replication state
mysql -h db-primary -u dbre_admin -p -e "
SHOW REPLICA STATUS\G
SHOW STATUS LIKE 'Rpl_semi_sync%';"

Isolates unindexed long-running queries (>1000ms) and checks client connection pool limits across MongoDB clusters.

# 1. Capture operations running longer than 1000ms across all shards
mongosh "mongodb://dbre_admin@mongo-primary:27017/admin" --eval '
db.currentOp({
  "active": true,
  "secs_running": { "$gt": 1 },
  "ns": { "$ne": "local.oplog.rs" }
}).inprog.forEach(op => {
  print(op.opid + " | " + op.ns + " | " + op.secs_running + "s | " + JSON.stringify(op.query || op.command));
});'

# 2. Audit client connection exhaustion and available worker threads
mongosh "mongodb://dbre_admin@mongo-primary:27017/admin" --eval '
const status = db.serverStatus();
print("Connections: Current=" + status.connections.current + ", Available=" + status.connections.available);
print("Network Requests Pending=" + status.network.numRequests);'
