This is very common frequent ask question (FAQ).
What E-SPIN Network System Application Monitoring (NSAM) WhatsUp Gold (WUG) capable to monitoring is depend on the edition of license (ie whether had that feature in the edition), and what customer had and capable to provide those feature required support (eg, for NetFlow, need device support NetFlow on the device).
For the feature entitlement, it tie to the edition of the software or addon / plug in entitlement. In general to speak, below is the typical most asked monitoring requirement across infrastructure network/ system and application monitoring:
Network Device (such as switch, router, firewall) – If PING monitoring only, just device up/down; but if SNMP monitoring, then ping device up/down – cpu utilisation – memory utilisation – interface utilisation – hard disk utilisation) : Special remark: be note for certain device do not had hard disk, in such case will not had disk utilisation since do not had SNMP (ie MiB and OID for pulling those information from the device). Wireless device and storage device like Access Point, SAN fall under this category.
Server/workstation/pc system – if PING monitoring only, just device up/down; but if SNMP monitoring, then system up/down – cup utilisation – memory utilisation – interface utilisation – hard disk utilisation): special remark: by default interface utilisation is turn off due to system nature no network device. But it can be turn on if required, in general to speak, it all about MiB and OID available for pulling those information from the system.
System Services – for server system, typical requirement is no just monitoring for the server box running or not, but the service inside the server, example, MSSQL services, SMTP email services etc. As long as SNMP enable device can show up what the running services the box, it can add in additional active monitor for the service to monitor those service on top of box health.
Virtualization Environment monitoring – for customer on Vmware platform, on top of monitoring each virtual machine like physical, it can leverage Virtual environment monitoring (if the customer license entitlement for this feature) for monitoring for virtual environment provide insight into virtual monitoring parameter include the ESX host, etc (for more about this please refer WhatsVirtual feature set).
Application Performance Monitoring (APM) – for customer had the APM feature set entitlement, can configure and monitoring enterprise application (typically a enterprise application will include web server, database server, application server in one or multiple box and perform custom monitoring as single application based on parameter required reading form the SNMP MIB and OID). For more about this please refer APM feature set.
