Windows Server 2019: Module 8 Section 2: Capacity Planning & 8.3 Use Server Manager to review event logs

What is a best practice no matter the organization

future capacity planning

What does capacity planning focus on

assessing server workload, the cumber of users that a server can support, and the ways to scale systems to support more workloads and users in the future.

What are some additional capactiy requirements

adding more servers

adding hardware

reducing application loads

reducing the number of users that connect to a server(done by distributing users to multiple servers)

what is a performance bottleneck

when a computer is unable to service requests for a specific recourses.

Some ways to fix a bottleneck

run fewer applications

adding resources to the computer

Key server hardware componets

Processer(CPU), Memory(RAM), Storage, and Networking

Servers have multiple

Processors

1 billion processor cycles per second is equal to

1 GHz

Redundant Array of Independent Disks(RAID) can be used to

optimize access times

WIndows Server 2019 does not reject memory request by applications instead it performs

paging

what is paging

Windows Server moves data and programs in memory that are currently not in use by the processors to the paging file, which in an area on the had drive. But if a hard drive is slow this can cause a negative effect and you would need to add more memory.

When planning network capacity you must think of

every device such as routers, switches, asa’s, and hubs.

What are some ways to monitor DNS

DNS Server Role and DNS console

How to monitor DHCP

DHCP Manager Console

With a server that has VMs on it you must monitor

both the host server and the VMs

Hyper-V Resource Metering allows you to

monitor resource consumption on VMs

What are some things you can monitor on VMs

Average GPU and memory use(as well as max and min use)

Incoming and Outcoming network traffic

to view Hyper-V vm resources uses you must use

PowerShell since there is in GUI

cmdlets for PowerShell Hyper-V vm monitoring

Enable-VMResourceMetering - This cmdlet starts collecting data on a per-VM basis.

Disable-VMResourceMetering - This cmdlet disables resource metering on a per-VM basis.

Reset-VMResourceMetering - This cmdlet resets VM resource-metering counters.

Measure-VM - This cmdlet displays resource-metering statistics for a specific VM.

Windows admin center can do many things similar to Server manager such as

Overview tab - task manager like tool

Performance monitor - allows you to monitor performance in real time

Server Manager provides what for monitoring multiple remote servers

centralized event logs

What are some cirtea you can filter logs by

time it was logged

even level

specific event IDs

Computer on which it occurred

What does Event log Subscriptions do

allows a single server to collect copies of events from multiple systems

Types of Even log Subscriptions

Collector-initiated

Source computer-initiated

What is a collector-initiated subscription(pull subscription)

identifies all the computers from which the collector will receive events and typically pulls events from these computers. These events are then stored on the collector computer.

What is a source computer-initiated subscription(push subscription)

source computers push events to the collector.

To use event log subscriptions you must configure what are the collecting computers

forwareding

what must be present and running on the servers for forwarding to work

WinRM service and Wecsvc

how to enable subscriptions

On each source computer, run the following command at an elevated command prompt to enable WinRM:

winrm quickconfig

On the collector computer, enter the following command at an elevated command prompt to enable Wecsvc:

wecutil qc

Add the computer account of the collector computer to the local Event Log Readers group on each of the source computers.

How to configure a source computer

Run the winrm quickconfig command.

Open Computer Management, and then add the computer as a member of the domain local Event Log Readers group.
