Network management los angeles

Network management is the key to running a smooth operation. Network administrators know that their job and salary depend on a smooth running network. Management software helps alert the administrator of any potential problems.

Network Performance Monitoring Tools

* Network Performance Monitor - Monitors and alerts on availability, bandwidth utilization, CPU load, memory and disk space utilization on hundreds of network elements. * Real-Time Bandwidth Gauge - Provides auto-publish to the Web and historical graphing. * SNMP Graph - Monitors any SNMP managed device. * Real-Time Interface Monitor - Displays many statistics from routers and switches simultaneously. * Advanced CPU Load - Monitors the real-time load on routers. * CPU Gauge - Displays a single switch, server or router's CPU performance

Monitoring Exchange Performance and Optimization

Electronic mail is probably the most mission-critical application on the Internet today! Most businesses use email for communication with suppliers and customers - proposals, support requests, meetings, are all scheduled over email, and any downtime, non-delivery, extremely delayed delivery of email can severely impact the operation of a business. Consequently, monitoring and managing email servers effectively is extemely important for most corporations.

Theses are a few keyword terms for Exchange monitoring that every system adminstrator should have in their tool box:

If any of the Exchange server queues indicating a malfunctioning/slow-down of the server? Are RPC requests from MAPI clients being queued for processing at the Exchange server, or any change in the server's processing rate of RPC requests? Is there any queue buildup at the Epoxy layer between the Exchange store and Microsoft IIS? Are many retries being attempted for mail delivery? Is there a significant slowdown in local mail delivery time? What is the delivery time of mail to remote locations? Are there any critical errors related to Exchange in the Windowsevent logs? Is the exchange database configured correctly? Are there enough log buffers, and is the cache hit ratio within acceptable limits?

Process Monitoring Are the critical Exchange processes working? Is any process consuming excessive CPU or memory? Is there any unusual activity on the server (e.g., backup jobs, antivirus software) that can be impacting the Exchange server's performance?

Mail Traffic Monitoring What is the workload on the server in terms of RPC requests from MAPI clients like Outlook? Is there any unusual increase in mail traffic activity? What are the peak times and how many users are connected at that time?

Network Monitoring Are there network congestion/collision issues that could be slowing performance as seen by end users? Is there excessive queueing of requests on any of the network interfaces of the system hosting the Exchange server?

Memory Monitoring Does the system hosting the Exchange server have sufficient free memory? Are there excessive page faults occurring that could be impacting performance?

Disk Monitoring Is there a disk bottleneck on the system hosting the Exchange server? Are there requests queued on any of the disks on the system hosting the Exchange server? Are disk read/writes to any of the disks on the system very slow? Is the load on the disks balanced well or is one of the disks handling a much higher load than the others?

CPU Monitoring Is the system CPU on the Exchange server very heavily used? Which process(es) are taking up CPU? Is there a specific time period daily when system usage tends to peak?

Active Directory Monitoring Is the Exchange server able to communicate with the Active Directory server? Is the length of the categorizer queue which handles requests to the global catalogs unusually high?
