The fees for the log manager are levied on a monthly basis with no limit on the number of data sources. However, there are three plans. The cheapest of these is free to use but is limited to processing just MB of data per day and has a retention period of seven days. The Standard plan processes 1, 5, or 10 GB per day and has a retention period of seven or 15 days. The top plan, called Pro , can process up to G B per day and offers a retention period of up to a year. Sematext offers the Standard plan on a day free trial.
Omantek opEvents is a log file manager that is able to collect and consolidate log messages from a Range of sources, including Syslog and Windows Events. The opEvents system installs on-premises and its dashboard gives you the opportunity to identify log metrics, such as the reporting rate, and set alerts on unusual statistics. The tool will reorganize incoming log messages into a neutral format and then store them together in files with meaningful names, such as by data, source, or both.
These files are regularly rotated and held in a directory structure that makes finding a relevant event easy. The dashboard includes a data viewer that includes a sort and filter facility for data analysis. It is possible to identify log messages that pertain to a specific device and then analyze its performance based on reported status records.
The screens of the opEvents dashboard are colorful and attractive. They combine log records with summarizing data graphics. The service allows you to set your own rules by building queries that look for specific events of combinations of actions on a specific device.
The data viewer can highlight conversations with particular endpoints and group together log records for specific applications. If you create a search for a specific indicator, you can then work through and open a series of log files and apply that same query to each of them. The opEvents system supports manual event investigations , so it is specifically aimed at system technicians who know what signs to look for in the large volume of log data that gets generated by a typical system.
The opEvents system is not a standalone tool. So, you need to install that system first. The opEvents is free to use on a 20 node network. You can get a day free trial of the full, unrestricted system. Log management is an integral part of systems administration and so Paessler made sure to include a log monitoring section in PRTG. Each monitoring interface in PRTG is called a sensor.
Two sensors manage logs. This includes application alerts and operating system notifications. The sensor monitors the rate of log messages rather than the contents of each message.
However, it does categorize those alarms by source or event type. The sensor will generate an alarm in the dashboard if the rate of event log messages escalates.
Those notifications can be sent to you in the form of an email or an SMS message. You can customize alert notifications so that they are sent to different team members according to severity or source. The Syslog Receiver sensor receives, monitors, and saves Syslog messages. You can set the conditions that trigger alerts, and you can decide to whom and how notifications are delivered.
Paessler PRTG is free to monitor up to sensors. If you want to use the tool to monitor your entire network, you will need a lot more sensors and that level of service is charged for. You can get a day free trial with unlimited sensors. Download Free Trial Splunk is a comprehensive log management solution for macOS, Linux, and Windows. The system is a well-known utility within the system administration community. Splunk, Inc produces three versions of its network data monitoring software.
This is a network management system rather than just a log file organizer. Fortunately, Splunk is also available for free , making it into our list of Cronolog alternatives. The free Splunk is restricted to input file analysis. You can feed in any of your standard logs or funnel real-time data through a file into the analyzer. The free utility can only have one user account, and its data throughput is limited to MB per day.
A data sorting and filtering utility is built into Splunk, and you can write out to files from the analyzer. These features can emulate Cronolog by dividing log records by date and writing each group out to new files.
This cloud-based utility acts as a hub for log file information gathered by an agent on your system. The hosted log management tool can collect live data streams to create log files as well as monitor and manage existing files. One of the data sources that Fluentd is written to manage is the logging system of Apache. Results from log record analysis can be made to trigger alerts, but these have to be processed by Nagios, or a Nagios-based monitoring system.
Fluentd is an open-source project so that you can download the source code. This tool is free to use. The Fluentd website is the source for the program, and it is also the location of community pages where you can get help and advice on running the tool from other users.
The core package can be extended through plugins written by other community members. Those plugins are usually free of charge. You can use many other free interfaces as a front end for Fluentd, such as Kibana. Logstash is a log creation facility produced by Elastic. The core element of the Elastic Suite is Elasticsearch. This is a searching and sorting utility that can process data from several files into unified results. Elasticsearch can be integrated into other tools and is available for use with many of the other utilities in this list.
The functions of Logstash can be tailored to emulate Cronolog. The facility creates source files for analysis by other tools, such as Elasticsearch. The power of this tool is that it can collate data from several different sources.
The capabilities of Logstash include file parsing, so you can use this function to split up your log files by date. The output of Logstash can be formatted to suit a long list of utilities for analysis or display. It can also be written to a plain text file on disk, which is exactly what Cronolog used to do. Elastic produces Kibana, which is an excellent free front end for any data gathering tool. The full capabilities of Kibana go way beyond the file parsing function of Cronolog.
However, the full range of commands available with Kibana includes basic file management that can split out any log file by date. Kibana has a command language console that lets you create scripts and programs to process files. The interface includes time-based analysis tools including filters, so you can quickly isolate records in a log file that relate to a specific date.
Raw data, graphs, and other visualizations can be written out to files or used to generate reports. Standard reports can be scheduled to run periodically, so creating a filter by date and setting it to run daily and output to a plain text file would give you exactly the same results that you used to get from Cronolog. The benefit of using Kibana is that it can give much more assistance than Cronolog could.
You can compare data from different sources and visualize the information from all of your system log files to analyze performance and forecast capacity requirements. To get a full data management facility, you should probably use Logstash to collate source data, Elasticsearch to sort data, and Kibana to display results.
Kibana has plenty of data sourcing and manipulation facilities so that it could be used as a standalone data analysis tool. Graylog is a free, open-source log file-based system that can give you a lot more functionality than just a log archiving utility.
This log management facility can work with any logs. You can feed data into it from other sources by channeling system reports into a file, thus creating your own logs. Action scripts can forward log data to the screen, to other logs, or on to other applications. The dashboard shows data in the form of histograms, pie charts, line graphs, and color-coded lists.
The interface includes a search and query function, which allows you to filter log records to get information on specific types of events or specific sources. Those overall views of data are not your only option because you can drill down and see the detailed records that created a summary. This makes Graylog a data mining tool. Alert conditions can be customized, and you can write actions to be performed in the event of alerts arising.
These actions include executing scripts or notifying specific team members by email or by Slack message. This is an amazing and very comprehensive tool that can automate your log file processing and automatically execute fault resolution.
The two essential elements of Cronolog are that it could split up log files by date and that it could be run automatically. XpoLog includes both those functions. This is an excellent improvement on Cronolog, however, because XpoLog includes a lot of other functionality. The tool could be improved upon, however, if the user interface were made easier to navigate. You can access a live demo of this tool here. This tool focuses on log management while giving users access to a surprising range of network observation capabilities.
LOGalyze uses an intensive and extensive search function to detect your real-time events. This log viewer is also able to define your events, comparing them to existing log information and alerting you when anything unusual occurs. With the ticketing system, you can close events quickly and efficiently. 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. 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 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.
A day free trial of the unlimited version of PRTG is available. This tool is user-friendly, cost-effective, and scalable. With plenty of useful features, including the ability to respond to IT events with automated syslog message responses, this tool helps you address issues quickly and proactively.
