Written by Clifford This article outlines basics of using Anturis in monitoring IT systems running on AWS. This mode requires that customers not install any custom software to avail a monitoring service. This requires the installation of a private agent which runs as an internal system service. For the purposes of this article, the operating system is Ubuntu 14.04 LTS x86_64. As an example of external public-agent-based monitoring, lets configure website monitoring with a focus on response time....

Written by Clifford Devices in an infrastructure need to be kept within a normal temperature range. This is one of the key aspects of data center environmental control. The CPU is one of the most critical server components. Its also one of the most vulnerable due to its propensity to overheat. As a result well arrive atfree continuous CPU monitoring, with a web graphical interface. The steps might differ depending on your hardware and operating system controls....

HTTP defines the format of request and response messages between a client and a server. The action to be performed by the server is indicated using one of the methods defined by HTTP. For example, theGETmethod is used to retrieve data (such as a web page). Whatever method is used in the HTTP request, the first line of the response is the status line. TLS/SSL are cryptographic protocols for secure communication over computer networks....

The current standard is version 4 revision 1 of the protocol (IMAP4rev1). Most IMAP clients generally leave messages on the server unless the user decides to delete them. This enables multiple clients to connect and manage the same mailbox on an IMAP server simultaneously. The default port number that an IMAP server listens on is 143. The server requires a username and password to authenticate a client. TLS/SSL are cryptographic protocols for secure communication over computer networks....

Written by Clifford The world is running out of IPv4 IP addresses and will soon only issue IPv6 addresses. What does the system administrator need to do to make the transition to this new reality? A bit can be 0 or 1, so there are 2^32= appx 4.3 billion possible IP addresses. But in fact ISPs do not have many left to sell. Brazil has some still available from its allotment....

This metric can affect overall performance of the underlying OS, if the JVM consumes all available memory. Heap memory usageis the amount of memory that the JVM allocates for objects used by the running Java system. Unused objects are regularly removed from the heap by the garbage collector. Non-Heap memory usageis the amount of memory allocated to the method area and the code cache. The method area is used to store references to loaded classes....

OS performance monitoring helps detect small problems before they become large ones. It maximizes availability, which maximizes customer satisfaction. Anturis agent itself is a small-footprint background Linux process. The Linux agent supports auto-updates, so its easy to keep it up to date. Graph and receive alerts about virtually everything from CPU temperature to the QoS of a video stream. Seamless agent installation Linux Agent can be installed in two ways....

Written by Clifford Aprocessis an instance of a computer program that is being executed. Some processes can start child processes. By default, child processes exist until they are terminated or until the parent process terminates. Most processes are idle much of the time. Most modern programs create objects in the main memory and operate on them. This is known as a memory leak, which is a common problem for server software....

Create Your Account > Alog fileis used to record events that occur while a program is running. For example, server software maintains log files to keep track of all client requests. The depth of analysis depends on the amount of data that is logged. Most software enables you to pick the level of detail for log files. Syslog is not supported on Windows servers. However, there are tools that can forward Windows Event Log data to a syslog server....

Ping Ping monitoring verifies connectivity by sending packets to remote hosts and receiving responses. Requests are sent and received via ICMP (Internet Control Message Protocol) echo request packets and echo replies. Ping validates connectivity, verifies IP addresses, and can be used to measure response time. Anturis supports IPv6, the most recent Internet Protocol. Ping can be used to access IPv6 configurations. SNMP Simple internet Management Protocol (SNMP) enables communication between internet devices....

Written by Clifford Anturis provides multiple monitoring locations, permitting web server availability testing globally. Alerts can notify you of issues at any point in your connection. Ensure your services are up 24/7 around the globe.

HTTP/HTTPs Checks website availability, response time, and response content (header, body). For HTTPS checks SSL certificate expiration and time to expiration. Ping Checks server reachability via ICMP ping and ping time. Full page load Checks full page load time. POP3/POP3s Checks POP3(s) mail service availability and response time. SSL and TLS are supported at transport and protocol levels. IMAP/IMAPs Checks IMAP(s) mail service availability and response time. SSL and TLS are supported at transport and protocol levels....
