This document discusses website monitoring strategies including tracking key metrics of web servers like Apache, IIS and Nginx; optimizing individual URLs for user experience; using synthetic monitoring to simulate web transactions; and detecting unauthorized content changes. It provides overviews of monitoring various web servers and their key performance indicators. It also describes optimizing the user experience by monitoring URL sequences, implementing real browser monitoring, and using web transaction recording. Finally, it discusses monitoring website content to detect hacks and defacement.

1. Applications Manager
Building the right Website Monitoring Strategy

2. 2. Optimizing individual URLs for better user
experience
4. Detect unauthorized content changes in
your website
AGENDA
1. Track key metrics of Apache, IIS, NginX,
Nginx Plus.
3. Simulate web transactions with synthetic
monitoring

3. • Web applications served from an
application server
• Database servers or data stores
WEBSITE MODEL OVERVIEW

4. 1. WEB SERVERS AND THE REVERSE PROXY: APACHE, IIS, NGINX,
ETC.
Web Server Monitoring All You Should
Know

5. WHY WEB SERVER MONITORING IMPORTANT?
Poor Web server performance
Performance bottlenecks in Apache web server cause
websites to load web pages (HTML, CSS, rich-snippets)
slower
Web server running out of capacity
Inability to see the number of web server requests and
traffic spikes to the website makes server capacity
management difficult
Supported component failure
Poor performance of the associated IT infrastructure
(Operating system, DBs VMs)
Helps track the popularity and growth of websites
Traffic and connection metrics offer direct insights into
site activity thus helps admin to develop plans for
website scaling

6. SUPPORTED WEB SERVERS
Web servers are responsible for loading and delivering web pages to the end user. In order to make sure
your websites and web servers are always available, webserver monitoring is crucial.

7. APACHE WEBSERVER MONITORING: GETTING STARTED
Apache Web Server is an open-source web server creation, deployment and management
software to host websites.

8. DISCOVERING YOUR APACHE SERVER
Application
availability
Error count
Request
Rate
Application &
Server CPU

9. • Response time
• Request details
• Busy Servers
• Bytes transferred
• Availability
KEY PERFORMANCE INDICATORS OF APACHE
Apache server monitoring empowers users to ensure low latency and continuous availability by tracking the
amount of load the Apache workers weigh in on the CPU round the clock.

10. Apache Request Details
This metric is specifically used to measure the server performance. Used in combination with other metrics,
it can be used to determine how the server performs under different loads.

11. BUSY SERVERS
Measures the amount of information being transferred in and out of the server. This metric can be used as
an indicator of server performance, relative to constraints such as network infrastructure.

12. IIS SERVER MONITORING

13. DISCOVERING YOUR IIS SERVER
Application
availability
Error count
Request
Rate
Application &
Server CPU

14. • Response time
• Application pools
• Website statistics
• Worker Process
• Availability
KEY PERFORMANCE INDICATORS OF IIS
Applications Manager helps in proactively monitoring the IIS web server. It connects to the IIS server and
checks for the availability, response time, website stats and status of the various web applications in the
pool at regular intervals of time.

15. IIS WEBSITE STATISTICS
Applications Manager helps you in being proactive to deliver a superior user experience by keeping tabs on the
key website stats like availability, response time, bytes and files transferred per second, connection statistics,
etc.

16. DRILL DOWN APPROACH TO WEBSITE STATISTICS
Monitors the bytes and files transferred per second in your website. Tracking if it is beyond the capacity is
necessary as this gives a picture of how fast your website is responding.

17. ESTIMATE THE USERS ON YOUR WEBSITE

18. IIS APPLICATION POOLS & WORKER PROCESS
Application pool allows one to isolate the web applications deployed in IIS for better security, availability,
performance and to keep it running without impacting others.

19. NGINX MONITORING
Nginx is a popular open source high-performance web server for larger web setups. It is known for its rich feature
set, simple configuration, and low resource consumption.

20. DISCOVERING YOUR NGINX SERVER
Application
availability
Error count
Request
Rate
Application &
Server CPU

21. • Response time
• Active connections
• Requests per second
• Requests in various states
• Availability
KEY PERFORMANCE INDICATORS OF NGINX

22. MONITOR NGINX ACTIVE CLIENT REQUESTS IN VARIOUS
STATE
Monitor how many client requests your servers are receiving and how those requests are being processed.

23. • NGINX Plus is a software load balancer, web server, and content cache built on top of open source NGINX.
• API model should be enabled in Nginx Plus for monitoring

activity-monitoring/#configuring-the-api
NGINX Plus

24. NginxPlus Functioning
• Nginx Server
• Server Zones (Virtual Servers to route the
request, return specific error code, rewrite
URI)
• Upstream Zones (Clusters) -> Upstream
Servers (Load balancing pool of servers)
Different load balancing method used to pick a
server and allocate request. By default Round
Robin

25. METRICS MONITORED IN APM
Overview
• Overall Connection stats
• SSL Connection
• HTTP Connection
HTTP & TCP SERVER/UPSTREAM
ZONES
• Incoming Traffic
• Discarded requests
• Response Code Splitup
• Outgoing traffic

26. METRICS MONITORED IN APM
HTTP & TCP Upstream Server
• Response Time
• Throughput
• Health (Checks Failed &
Status)
Caches
• Hit Ratio
• Cache Size
• Responses Read (Valid &
Expired) Responses Written

27. 2. OPTIMIZING INDIVIDUAL URLS FOR BETTER USER EXPERIENCE
Website Monitoring

28. HTTP URL Monitor
 Average and
current response
time
 Response time
split up:
 DNS time
 Connection time
 First byte time
 Last byte time

29. WHY URL SEQUENCE MONITORING REQUIRED?
 Site is not reachable due to too many
people accessing it simultaneously
 Clicking on the page leads to HTTP 500
internal server error
Slow Loading Page?

30. WEB TRANSACTION RECORDER FOR URL SEQUENCE AND
RBM

31. HTTP URL SEQUENCE Monitor

32. • Capture errors, network
requests, page load details and
other metrics in your web
applications
• Set up end user monitoring
agents in branch facilities to
check the availability and
performance of your distributed
applications
3. SYNTHETIC TRANSACTIONS MONITORING FOR DYNAMIC
WEBPAGES

33. UNDERSTANDING THE END USER JOURNEY

34. INSTALLING EUM AGENTS IN YOUR BRANCH OFFICES OR
CUSTOMER LOCATIONS

35. REAL BROWSER MONITORING
Mimic User Interaction
Monitor the Real Website
performance around the world
Reduce blame game between
application and network team

36. • Launch the web
transaction recorder
• Enter the host and SSL
port of Applications
Manager
• Enter the Applications
Manager credentials and
proceed with the
recording
RECORDING A WEB SCRIPT

37. MONITOR CRITICAL WORKFLOWS

38. DEEPER VISIBILITY INTO MULTISTEP USER INTERACTIONS

39. • Use our EUM agent to understand global application performance through easy to use graphs and
charts. Determine if performance is excellent, good, moderate, poor or bad when accessed from
different countries.
Measure web application performance across
globe

40. OPTIMIZE FRONT END WEB COMPONENTS

41. • It depicts the series of actions that occur between a user and a server until a Web page is displayed
in a end user’s browser.

APPROACH

42. • Playback scripts including
screen, keyboard, and
mouse interactions
performed by users
• Meet SLAs by ensuring
accurate performance of
your web applications from
all geographical locations
THE NEED FOR SYNTHETIC TRANSACTION MONITORING

43. 4. WEBSITE CONTENT MONITORING TO DETECT UNAUTHORIZED

Protect your website from hackers
Rapid discovery of quality issues, outages

44. WEBSITE DEFACEMENT
 Website
defacement refers
to unauthorized
hacks on your web
page or entire
website
 Negate any impact
on search engine
page rank and
traffic due to web
page defacement.

46. LIST OF WEBSITES MONITORED

47. MONITORS WEBSITE HACKS USING STANDARD CHECKS
 Scan your entire

 Identify changes
in HTML
elements - 'href'
or 'src'attributes
