Why server monitoring is important

 


Servers are the backbone of your business. To minimize downtime and to ensure peak performance of your website and services, constant monitoring of your server infrastructure and your data center is vital.
By tracking the uptime, health, disk space and performance of your servers, you can prevent outages and identify bandwidth hogs. In addition, you are laying the foundation for delivering a great service to your customers, through a fast-loading and constantly available website.

Professional unified server monitoring software:
That's PRTG

 

 

 

 

iWhat is a sensor?

In PRTG, “Sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

PRTG monitors all types of servers – even in distributed networks. Here are a few examples of the kinds of servers for which PRTG provides predefined sensors so you can get started with your server monitoring at once:

Mail

Mail Server Monitoring

Mail servers, in particular, are sensitive issues for companies. When mail server glitches occur, employees are quick to complain, putting the support department under intense strain. With PRTG, you can monitor your mail servers permanently and be alerted in a timely fashion. IMAP, POP3, SMTP, and many more: we supply more than a dozen sensors for your mail server monitoring.

Web Server Monitoring

Web Server Monitoring

Website performance is a deciding factor for many companies – all the more so when they offer products and services via their websites. Downtime is costly, right from the very first second. That’s why PRTG also makes a whole range of sensors available for your web server monitoring (IIS, Apache, and more).

Database Server Monitoring

Database Server Monitoring

Practically all company information is stored in databases. When it comes to databases, performance is also the basis for the effective functioning of each and every department. PRTG thus offers a variety of sensors which are available for immediate use. These include sensors for the monitoring of MySQL, Microsoft SQL, and Oracle SQL. You can selectively choose HTTP content or perform database queries.

File Server Monitoring

File Server Monitoring

If firms can’t access information, then nothing works. One of the tasks of administrators is therefore to ensure the file server runs smoothly, and as with other servers, avoid crashes. It’s not uncommon for administrators to search, say, for a specific FTP server monitoring tool. But PRTG has you fully covered in this area as well. For you get around 20 sensors just for your file server monitoring. Monitoring of NAS devices and storage area networks (SAN) is also supported by PRTG.

Defining and understanding server monitoring

Information in real time

Information in real time

Server monitoring lets you monitor your servers in real time with regard to availability, accessibility, capacity, and overall reliability. With server monitoring, your servers are checked at regular intervals to ensure you always know their status.

Improve stability

Improve stability

Sysadmins monitor their servers because they wish to improve the stability and performance of their networks. If certain threshold values are exceeded, you’ll receive a warning message so you can take action at once. Our monitoring service helps you complete your everyday tasks. It provides you with a constant overview of your server resources.

Basis for analysis

Basis for analysis

Sysadmins analyze the values they receive from their monitoring software to develop courses of action. When studied over the long term, these values can help optimize various aspects that are responsible for the performance of your network, such as capacity planning. The PRTG reports feature is extremely useful for such optimization.

3 good reasons for PRTG as your server monitoring software

 

 

iA server is a computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network. In theory, whenever computers share resources with client machines they are considered servers. There are many types of servers, including web servers, mail servers, and virtual servers. Read more ...

An Integrated Solution

An Integrated Solution

Whether just a few servers or a large server farm: PRTG adapts dynamically to the size of your server landscape. And should you acquire more servers, all licenses are individually upgradeable. PRTG is an integrated solution: whether processors, memory, cooling fans, power supplies, or other components, our Server Monitoring Tool simultaneously monitors your servers as well as your entire infrastructure. PRTG immediately recognizes if a router or switch fails and causes a disruption in the server. Even virtual servers are recognized automatically and included in the monitoring.

Prompt Alerts

Prompt Alerts

Servers are the main elements of every IT infrastructure. Without them, a company is more or less unable to function. PRTG ensures system failures are as short-lived as possible – or even prevented in advance! Thanks to the e-mail or SMS alert feature, you’ll know straight away if complications arise. Locate errors directly: this will save you lots of time. You can even define the alert threshold values yourself. This means you’ll be notified before a shortage leads to a crash.

Capacity planning

Capacity planning

PRTG helps out with your capacity planning. Our Server Monitoring Tool lets you to promptly recognize when in the medium to long-term it will be necessary to increase your capacities. Our dashboard presents compelling charts which are perfect for convincing your higher-ups with no technical know-how to expand your resources. The tool also features detailed reports providing a basis for scheduling and continual process optimization.

5 common questions regarding server monitoring

 

How can I best protect my company from server failures?


When a server goes down, the IT department must take action quickly. PRTG helps you improve the reliability of your servers. If the load of individual hardware components such as CPU, hard drives, or RAM rises, you’ll be notified at once. With PRTG, all threshold values are customizable.

What kind of information is collected by a server monitoring tool?


There are many monitoring and analysis tools on the market. We recommend weighing the pros and cons of each (such as PRTG vs. Nagios). PRTG is a network monitoring tool that continually monitors your entire IT environment. This environment includes servers, as well as devices such as switches and routers from all the major manufacturers. Add to that bandwidth, applications, quality of service, and much more.

How does the alarm get triggered when a server malfunctions or goes down?


You yourself set the threshold values which, when exceeded, activate the sending of a warning message. You can also define how the message is sent. Options include email, push notification, SMS, syslog messages, and more. The PRTG alarm is fully customizable. You can, for example, set up a more rigorous notification system for critical infrastructures (such as your servers) than for individual workstations.

Can I monitor external servers from one central location?


PRTG can monitor your servers from one centralized location, even if your devices are in different parts of the world. To do so, the monitoring tool uses “remote probes.” Remote probes allow for agentless monitoring, which means you can monitor IT environments found in different locations than your own.

Will monitoring have a negative impact on the performance of my network?


Our sensors use a variety of protocols to monitor your network. These include SNMP, WMI, and performance counters. Windows Management Instrumentation (WMI) is a commonly used standard created by Microsoft. Running WMI often puts great strain on a network’s load. If you decide to go with WMI, you’ll want to create as few WMI sensors as possible to ensure you don’t compromise the performance of your network. By contrast, the load generated by SNMP is quite insignificant, even for extensive monitoring with several thousand sensors. You’ll therefore rarely encounter drops in performance.

Here's what server monitoring looks like in PRTG

HTTP server error messages

Common server errors

Common server errors

All status codes beginning with “5” (5XX) are server errors – and therefore a problem. Server error 500 is a collective status code for unexpected server errors. All other server errors (501, 502, 503, etc.) are used to flag specific problems. Error 503, for example, means the website’s web server is currently overloaded or unavailable. For more information, see our knowledge base articles on HTTP status codes and sensors: Which HTTP status code leads to which HTTP sensor status? and Can I check for specific HTTP response codes with PRTG?

Web server monitoring

Web server monitoring

Error messages are clear evidence that web server monitoring makes sense. All the more so if the website is an important tool for the company. PRTG comes with a full range of HTTP sensors for monitoring websites as well as individual URLs.

„Hey Arne, how do I avoid false alarms during server maintenance?“

"In practice, repairs in the short-term will be necessary. While working, your monitoring will not trigger false alarms. The one-time maintenance window allows you to pause monitoring for each individual device or device group. For regular maintenance, with PRTG you can easily create an automated schedule."

Arne Seifert works in the Paessler AG Technical Support Department.

LDAP monitoring with PRTG

LDAP at a glance

LDAP at a glance

Lightweight Directory Access Protocol (LDAP) is a protocol that queries information from distributed directory services. Directories contain object-related data which can be read by monitoring tools such as PRTG. One such directory is Active Directory, the Microsoft service created for use in a Windows server environment.

Getting started with LDAP monitoring

Getting started with LDAP monitoring

PRTG comes with an LDAP sensor. This sensor attempts to connect to the LDAP server using authentication via the distinguished name (DN), and displays the response time of your LDAP server in the event that the connection and authentication are successful. Note: the LDAP Sensor cannot use LDAP via SSL. For more information, see the log monitoring page on our website.
