![]() ![]() Two of the mostly known standalone rule-based log analyzers are. mkdir swatch touch swatch/nf Next, add the following configuration in the file to monitor failed login attempts, failed SSH login attempts, successful SSH logins from the /var/log/secure log file. It is like uptime robot where you add your URL and it pings to the URL and trigger an email in case URL is down. Log analyzers are applications that parse log files and extract information from them. First create a swatch configuration directory and a file. tail -f /var/log/zabbix/zabbix_agentd.log Monitoring Web ScenarioĪlong with the apache logs, you can also any specific URL on a time interval validating the response and raising the alarm. In case you are not getting data, Please cross-check for zabbix.log on the host, if there is any issue. If you are getting permission denied, please provide the permission to Zabbix user to read this directory Make sure, the Zabbix agent is able to read the log file, this can be ensured by executing the following command su zabbix -s /bin/bash -c "tail /var/log/httpd/access_log" And you will get this Data under the Host graph along with other dataĬheck if Zabbix-Agent can access log file.You can add more items, it is just required log file path, aggregator method, and regex In Zabbix, you can use item but this only monitors 1 file and you have to specify the name of the file as well.second parameter is also a regex : 404, searching status code.unt : used for getting count with regular expression.Windows has various event log categories, and we could monitor the Security event log. But on Windows there is also a specialized logging subsystem, and Zabbix does offer built-in event log system support. logrt : used for getting logs with regular expression as here we trying to get logs for only 404 requests searching all files that end access_log Zabbix supports log file monitoring on Windows as wellthe topics we discussed in Chapter 11, Advanced Item Monitoring still apply.The Key contains multiple methods, for now, we are using these two.Most of the elements are self-explanatory like Name, type, update interval, History period, Application group.After creating a template, click on the newly created template, and under that click on Items.is a regular expression, describing the files that should be matched. Configuration > Template > Create Template Zabbix supports monitoring such a log rotation scheme with a separate item key.Either we want to get some logs like 404 requests or 500 requests.If we are talking about monitoring, it covers the aspect Check if Zabbix-Agent can access log file.In this example I believe these items should find for Zabbix: = Backup Failures =Ĭan you advise how possible to achieve this solution?įor any help I would be really appreciated. I found Zabbix can handle log file monitoring with similar command here but first need to find strings in the log file: log If results not OK then Zabbix triggers should send alarm. I need to find all items for monitoring and it's results. Status: OK, Check Time: Sun Oct 30 07:32:30 2022ĭetails: All processes of type w3wp.exe don't exceed memory limitsĭescription: Checks that the web site responds properly = IIS Application Pools Memory Usage =ĭescription: Checks the memory usage of the application pools that run under IIS (w3wp.exe) Status: Error, Check Time: Sun Oct 30 07:31:30 2022, Script: ĭetails: 1 missing process(es) found. Item Preprocessing with Regex - Zabbix Tutorials Item Preprocessing with Regex Video Lecture Description In this lecture, I add a pre-processing step to the item that instructs the agent to read the windows failed logon events. ![]() Status: OK, Check Time: Sun Oct 30 07:31:04 2022ĭetails: All queues have less than 15 elements. What happens when you execute the following command on the agents host: zabbixagentd -t /tmp/file.txt,C.s(0-9+.0-9),Windows. The queues are used to pass information between the applications The following log file information can be obtained from the content specified by the items. Status: OK, Check Time: Sun Oct 30 07:31:13 2022ĭetails: 0 total backup commands failed during the last day.ĭescription: Count Oracle queues sizes. Monitoring using the Zabbix Agent is called agent monitoring. I need to find strings in a log file with regex and later send output to Zabbix monitoring server to fire triggers if needed.įor example here is a part of the log file: = Backup Failures =ĭescription: Checks number of studies that their backup failed Log file monitoring items You can collect all new lines in the log file where you can do some filtering, matching based on the regular expression, extracting some specific output of your extracted log line, display it in the graphs, etc.
