VMware Data Collection Levels – Karalama Defterim

VMware Data toplama seviyeleri bulunmaktadır. Bu seviyelere Level 1,2,3,4 olarak değiştikçe log disk’in de tutulan alan boyutu değişecektir.

Varsayılan Log seviyesi Level-1’dir. Ciddi bir sorun olmadığı sürece varsayılan seviye değiştirilmemesi önerilir. Sorun çözülmesi için geçici olarak Level seviyesi artırılabilir.

Statics Levels tablosunu VMware’in yayınladığı makaleden alınmıştır.

Level	Metrics	Best Practice
Level 1	Cluster Services (VMware Distributed Resource Scheduler) – all metrics CPU – cpuentitlement, totalmhz, usage (average), usagemhz Disk – capacity, maxTotalLatency, provisioned, unshared, usage (average), used Memory – consumed, mementitlement, overhead, swapinRate, swapoutRate, swapused, totalmb, usage (average), vmmemctl (balloon), totalbandwidth (DRAM or PMem) Network – usage (average), IPv6 System – heartbeat, uptime Virtual Machine Operations – numChangeDS, numChangeHost, numChangeHostDS	Use for long-term performance monitoring when device statistics are not required. Level 1 is the default Collection Level for all Collection Intervals.
Level 2	Level 1 metrics CPU – idle, reservedCapacity Disk – All metrics, excluding numberRead and numberWrite. Memory – All metrics, excluding memUsed, maximum and minimum rollup values, read or write latency (DRAM or PMem). Virtual Machine Operations – All metrics	Use for long-term performance monitoring when device statistics are not required but you want to monitor more than the basic statistics.
Level 3	Level 1 and Level 2 metrics Metrics for all counters, excluding minimum and maximum rollup values. Device metrics	Use for short-term performance monitoring after encountering problems or when device statistics are required.
Level 4	All metrics supported by the vCenter Server , including minimum and maximum rollup values.	Use for short-term performance monitoring after encountering problems or when device statistics are required.
