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

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
