network monitoring – an overview

Network monitoring is needed in a system that persistently scrutinizes a computer network for sluggish or weakening components. It informs the network administrator via SMS or email in case of outages. It’s a part of network management . Whilst an intrusion-detection system scrutinizes a network for dangers from the exterior, a network monitoring system scrutinizes the network for issues sourced by overloaded or crashed servers. For instance, to know the status of a web server, monitoring software might sporadically send an HTTP request to obtain a page. For e-mail servers, a text message might be sent via SMTP & recovered by POP3 or IMAP.

TRANSCRIPT

Network monitoring is needed in a system that persistently scrutinizes acomputer network for sluggish or weakening components. It informs thenetwork administrator via SMS or email in case of outages. It’s a part ofnetwork management.

Whilst an intrusion-detection system scrutinizes a network for dangers fromthe exterior, a network monitoring system scrutinizes the network for issuessourced by overloaded or crashed servers. For instance, to know the status ofa web server, monitoring software might sporadically send an HTTP requestto obtain a page. For e-mail servers, a text message might be sent via SMTP &recovered by POP3 or IMAP.

Generally measured standards are response

time, accessibility & uptime, though both

reliability and consistency measures are

beginning to obtain popularity. The extensive

incorporation of WAN optimization tools is having

negative effects on most of the network

monitoring devices – particularly when it is about

observing precise end-to-end response time

since they restrict round trip visibility.

Internet server monitoring

Monitoring an internet server denotes that the

owner of the server always notified if one or more

of services go down. Server monitor could be

internal, for example, web server application

verifies its status and informs the proprietor if

some services go down, and external, i.e. some

web server monitoring firms verify the service

status with certain regularity. Server monitoring

can cover a test of system measures, such as

memory usage, CPU usage, disk space and

network performance.

External monitoring is more dependable, as it keeps working when the server totallygoes down. Also, manyserver monitoring tools have performance benchmarking,alerting abilities & the capability to connect certain entrances with automatic serverresponsibilities such as performing a backup. Also, it can comprise applicationmonitoring, such as verifying the procedures of programs such as Nginx, Postgres,Apache, MySQL and others.
