Monitor IT devices

Monitoring performance

Performance monitors Protocol

CPU, memory, disk, etc. SNMP/WMI for Windows

SNMP/Telnet/SSH for Linux, UX, or

Solaris

Microsoft application for Exchange, SQL,

and Active Directory

WMI

Vendor-specific monitors SNMP

Hyperv WMI

vCenter, ESX VMware VMware API

Xen server Xen API

Cisco UCS UCS API

Network devices/ other infrastructure

devices such as printer, UPS, etc.

SNMP

WAN latency check IPSLA (Cisco devices only)

VOIP latency check, mos, jitter, etc. IPSLA (Cisco devices only)

Server performanceHard disk usageo Free disk space vs. used disk space

o Current disk utilization

o Disk speed per second (reads and writes)

o Disk queue length (reads and writes)

CPU usageo Current CPU utilization

o % Privileged time

o Processor queue length

Memory usageo Current memory utilization

o Pages per second (faults, reads, and writes)

o Number of processes and each of their CPU and memory usage

Hardware monitor

o Sensor, power, temperature, voltage, etc.

o Supported vendors (HP and Dell)

Monitoring application performance for Microsoft SQL, Exchange, and Active

Directory

MS Exchange• Exchange services

• Active user count

• Messages sent per

second

• Messages queued for

delivery per second

• I/O database reads/writes

per second

MS SQL• SQL services

• Batch request per

sec.

• Current database

size

• Session request

• SQL cache memory

• Average lock wait

time

MS Active Directory• Active Directory services

• LDAP bind time

• LDAP searches

• LDAP authentications

• Replication objects

remaining

• Kerberos authentications

• NTLM authentications

Creating custom WMI monitors

• Windows server with access details

• WMI class

• Custom dial for performance monitors

• Monitor URL availability of both intranet and internet web

applications

• Configure the threshold for URL response times and trigger alerts

to get notified when website response becomes slow

• Configure match content and trigger alerts to get notified about

the missing string

• Associate notification profiles and get notified via email or SMS

• Configure proxy details for URLs behind a proxy o Settings > Basic settings > Proxy server settings

Monitoring website URL

• Monitor the availability of files and folders

• Configure thresholds for folder size and get notified whenever

that size is exceeded

• Configure filters based on file extensions to monitor only the

required files

• Configure thresholds for file size, age, or count and set an alert to

get notified when those values exceed the threshold value

• Perform automatic checks on files and folders that triggers alerts

when any changes occur

File and folder monitoring

Monitoring network devices (routers, switches, firewalls, and more)o CPU/memory usage

o Temperature, backplane utilization, active session count, etc.

Monitoring interface health

o Interface bandwidth usage

o Errors/discards

o Received and transmitted traffic

o Total bytes received

o Total bytes transferred

Hardware monitor

o Sensor, power, temperature, voltage, etc.

o Supported vendors (Cisco and Juniper)

Network performance

• SNMP-enabled device

• Vendor MIBs

o OpManager\mibs

• Mib-browsero Valid SNMP OIDs

• Custom dial for performance monitors

Creating a custom SNMP monitor

• Write a script to monitor a specific performance metric for which you

can't find a standard SNMP or WMI monitor

• Any script language that runs on a shell or prompt is supported o VB script

o Power shell script

o Perl script

o Shell script

o Python script

• Export/import existing script templates o Site to site

o Download one from ManageEngine (https://resources.manageengine.com/resources/forum/opmanager/custom-

script-templates)

Script monitor

Citrix XenServer

• Cisco UCS API

• UCS Chassis servers, rack mounts, fabric interconnect, fan modules,

etc.

• Reports

Cisco Unified Computing System

IPSLA monitoring

WAN performanceo Identify the network devices with high latency

o Identify the network paths with high round trip time

o Identify where the outage happened by viewing the hop-wise latency

graph

o Collect the IPSLA traps for events such as connection loss, threshold

violation for RTT, average payload, timeout, etc.

Prerequisites o A Cisco router with an IPSLA agent enabled

o iOS version must be 12.3 or later

o SNMP read and write community configured on the device

o Configure the device to send traps to an OpManager server

WAN performance monitoring

VOIP performanceo Jitter: The variation in delay between arriving packets

o Latency: The time taken for the voice packets to reach the

destination

o Packet loss: Data lost during transmission

o Mean opinion score (MOS): The standard for measuring codecs

and is rated on a scale of 1 to 5

Prerequisiteso A Cisco router with an IPSLA agent enabled

o iOS version must be 12.3 or later

o SNMP read and write community configured on the device
