What is a syslog?

Syslog refers to a universal standard for system messages. While syslog was originally implemented by Syslogd, a Unix utility, it’s now used by an array of IT equipment. This means almost every single piece of computing equipment you purchase will be able to send syslog messages.

Syslog messages can be directed to different log files based on the message’s severity level. To make the most of this information, the data should be processed or, at the very least, read. This is where a syslog viewer, or log viewer, comes in handy. A syslog viewer collects syslog messages from your network and displays them in a searchable and reviewable list, enabling you to monitor your network more effectively.

Top Syslog and Log Viewers List

1.   SolarWinds Kiwi Syslog Server (Free Trial)

Kiwi Syslog Server is built to help you centralize and simplify log message management across network devices and servers. This tool saves you the trouble of combing through hundreds of logs on a system-by-system basis—which can be an almost impossible task—by allowing you to manage syslog messages and SNMP traps from a single console. This solution is a Linux, Unix, and Windows log viewer, making it a versatile choice for most enterprises. Kiwi Syslog Server can collect syslog messages from a range of equipment types, including routers, computers, and firewalls.

With security threats lurking behind the scenes, the only way to ensure the safety and security of your servers and devices is to stay ahead of them. Kiwi Syslog Server delivers real-time alerts based on syslog messages, keeping you informed so you can act to safeguard against new and emerging threats.

Another great feature of this syslog viewer is the ability to rapidly respond to IT events with automated syslog message responses. You can trigger email alerts, run scripts, log to file or ODBC database, forward messages, and much more. These capabilities can amount to the difference between a problem getting out of control and halting it in its tracks.

This log viewer allows you to store and archive logs for regulatory compliance purposes. Log collection and retention are a crucial part of most compliance frameworks, and failing to meet requirements could have a significant impact on your business. Fortunately, this syslog viewer lets you schedule automated log archival and cleanup, helping you comply with HIPAA, SOX, PCI DSS, and more.

This log viewer allows you to view syslog data from anywhere, provided you have secure web access. This feature is especially beneficial to IT professionals, whose work often follows them wherever they go. The ability to filter and monitor log messages without restriction is useful, as well. The intuitive syslog viewer web console offers multiple customizable views, allowing you to choose how you want to view data.

Reviewing groups of log data for signs of malicious behavior can be an overwhelming task. Kiwi Syslog Server eliminates the labor associated with this activity by offering users access to advanced message filtering. With this utility, you can filter by host IP address, time of day, priority, or host name.

With many log viewers, log monitoring activities can lead to an inbox flooded with messages. Kiwi Syslog Server mitigates this risk with advanced message buffering, which, during heavy loads, introduces a buffer of up to 10 million syslog messages and 1,000 email addresses.

Kiwi Syslog Server also features an event log forwarding tool, which forwards Windows events to your syslog server. You can rapidly specify and automatically send events from servers and workstations. You can also export event data from Windows servers and workstations and specifically note which events you’d like to forward based on keywords, source, and type ID. You can also forward events to external systems to store, alert, and audit activity. Events can be sent to multiple servers over TCP or UDP.

Overall, Kiwi Syslog Server tops this list of the best log viewers because it delivers an impressive range of enterprise-grade features. With customizable dashboards and multiple filtering options, this tool is a great choice for companies valuing flexibility. This tool is highly user-friendly, with no initial learning curve or training required. If you’d like to give Kiwi Syslog Server a try, a 14-day free trial is available for download.

5. Paessler PRTG Network Monitor

Paessler PRTG Network Monitor is a comprehensive, sensor-based network monitoring system allowing you to customize your IT solution by choosing sensors to suit your individual requirements. A sensor is a monitored condition or status giving you insight into a specific element of your network, server, or system. PRTG’s Syslog sensor is called the Syslog Receiver. This sensor gathers syslog data traveling across your network and writes it to a database. Once the messages have reached the database, the records are managed according to the settings and conditions you define for the system. You should know that PRTG is not meant to replace a dedicated Syslog or SNMP trap receiver server but only displays these messages in the same environment as other network monitoring metrics (it’s not a replacement for Syslog Server itself).

You can have messages written to log files and use the dynamic PRTG dashboard to query them. These logs can even trigger actions under certain conditions, automating certain behaviors according to your preferences.

PRTG is a powerful and easy-to-use solution suitable for businesses of all sizes. It is, however, more cost-efficient for larger organizations that can afford the unlimited version of PRTG. If you’re a small company with minimal requirements, you can use up to 100 sensors for free, but most companies will exceed this limit quickly. A 30-day free trial of the unlimited version of PRTG is available.
