Query chaining and available fields

Fields available in simple searchThe search queries with field=value, word(s), phrases or logical combination of such without any use of "|" commands are defined as simple search. Each result row in the result of a simple search query can be taken as a set of field=value pairs and the actual logs. All the field=value pairs that are generated during normalization can be accessed. In addition, the following fields are added by default; log_ts, col_ts, device_name,device_ip,col_type.example: Users failing to loginlabel=User label=Login label=FailFields available in aggregation query resultsThere may be use-cases where a simple search doesn't suffice and there‘s a need to make aggregations based on one or more fields.Example:label=User label=Login label=Fail | chart count() as FailCount by target_userThe result of this query is a set of target_user values and the corresponding count, represented as FailCount. Only these two variables are available at this stage. If you want to make a searc

New in KB: How to handle a repo failed issue

We occasionally encounter cases where we cannot perform search because a particular repo has failed. In that situation, the search UI does not allow to make any searches if that repo is selected.What does "repo failed" mean?The "readiness" status of service responsible for searching in a particular repo (indexsearcher) is kept by central searching service (merger) in "alive" field for each repo. If the "alive" status of a repo is false in the config file of merger service, failed repo issue is seen when making search in that repo. This could happen if index searcher service for that repo is not running as expected or if the config file of the merger service is not updated according to the status of indexsearcher service.Mitigation:Whenever we get repo failed for a particular repo then it is always wise to check the logs for the indexsearcher service of that repo. tail -f -n 50 /opt/immune/var/log/service/indexsearcher_<repo_name>/current#replace <repo_name> with actual repo

New in KB: How to handle diskfull issues

Occasionally, we encounter issues where one of the mount point in LogPoint is full. The disk full conditions can be because of various reasons and it is of utmost importance to immediately free some disk so that LogPoint can function normally.Under disk full situations for /opt and primary repo path /opt/immune/storage locations, the log collection of LogPoint will be affected. DetectionTo detect the disk full situations, we can use the df command. df -hIn the output of this command, we can either look for the percent usage of each mount point or the available storage space. These indicators will help us detect disk full scenarios.MitigationNow, once we find out the problem in LogPoint is because of lack of storage space, we can dive deeper./opt path has 100% storage usedThe /opt mount point generally stores the necessary config files, service log files, mongoDB data and executables of LogPoint. For normal functioning of LogPoint it is critical to have some storage space available. Sin

New in KB: How to locate internal logs in LogPoint?

LogPoint stores its internal logs in the /opt/immune/var/log/ directory. Here is the description of the most useful log types inside that directory. Service logs/opt/immune/var/log/service/<service_name>/current This holds the internal service logs for each of the service of LogPoint. The current is the file in which logs are currently being written. The log files are regularly rolled over and are kept in the same directory as current.   Benchmarker Logs/opt/immune/var/log/benchmarker/<service_name>.log This contains the benchmarker data for various services. Not all services are benchmarked but important services like norm_front, normalizers, storehandlers, indexsearchers, premerger, various collector & fetchers have benchmarker data in this location.   System Metrics Logs/opt/immune/var/log/system_metrics/system_metrics.log This contains the operating system metrics that is regularly benchmarked in the system. It contains the information of CPU Usage, Memory Usage, N

New in KB: How to handle report generation failed ?

When we encounter cases when report fails to generate, There might be several reasons why this happened. Here are the list of things that can be attempted to handle report generation issues:Try running the report again Sometimes, report might fail when there is high load in the system. And just trying to run the report again after sometime might result successful generation of report.    Try increasing the heap_size of the report There is an option in the report template (in the right side) to increase the heap_size of the report job. Large reports (reports with more number of queries and large time ranges) require larger memory. So, increasing the heap_size incrementally from 512 MB to few GBs (up to 4GB) can be helpful.   Try searching for each of the query in the report in search, if they are working fine or not This is kind of a brute force way to figure out the problematic query or query which might be causing the report failure. If any of the repo is down or if any of the query h

New in KB: Troubleshooting LPAgent issues

Please follow the documentation for LPAgent at https://docs.logpoint.com/docs/logpoint-agent/en/latest/index.html carefully. Sometimes simple steps like processing policy or even the collector/fetcher are missed while configuring devices. Important Considerations for LPAgent:https://docs.logpoint.com/docs/logpoint-agent/en/latest/Important%20Considerations.htmlLogs should be coming into the system in few minutes once the setup is done, but sometimes we don't see any logs in the search.

Logpoint's status on CVE-2022-22965

CVE Summary : A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding.CVE Reference : https://nvd.nist.gov/vuln/detail/CVE-2022-22965Logpoint Summary :LogPoint uses spring framework in report engine, to connect with MongoDB using Spring-Mongo api. So, as transitive dependencies, spring-beans-3.1.2.RELEASE.jar is used. LogPoint does not have external exposure with this spring library as we are not using controller and accepting web requests via spring framework. Thus, we are not directly impacted by this vulnerability. We are also safe because of the following:We are not using any spring web framework. We are using Java 8 not Java 9 and beyond. We are not packaging in WAR and not using any servlet containers.DirectorFor LPSM, the impact is the same as for LogPoint. For other components in Director, we are not using spring libraries. We are still using Java 8 all across the product line.SoarCurrently any SOAR containe

New in KB: Optimization of Process ti() based queries

Process ti is used in Logpoint to use the search time enrichment functionality from the threat intelligence database. This can be done by using | process ti(field_name) in the query.Example:source_address=* | process ti(source_address)  This query will enrich all the logs which match the source_address field with the ip_address column present in the threat_intelligence table. This source_address to ip_address (and other) mappings can be configured from the threat intelligence plugin's configuration settings.  The search query above takes a large amount of time to complete if there are a large number of logs present within the search time frame. We can optimize queries by filtering logs before piping to process ti() part in the query.Example:norm_id=* source_address=* | process ti(destination_address)This query can be optimized by using another query:norm_id=* source_address=* destination_address=* | process ti(destination_address)This query will select only the logs that have destinati

LPA configuration not being pushed

There may be numerous reasons for the LPA configuration to not be pushed from LogPoint to the agents. The following are some of the things that you can easily check before contacting LogPoint Support.Check if the Windows machine is actually running or not. This might seem trivial, but there are instances where the windows machines are not functioning in the first place. Run the telnet command on the device for port 7994 and 7995. Since these are the ports via which the configurations are pushed, this might be an issue with the lpagents which are deployed on the log source. You can also check if  ports 7994 or 7995 are open on the device's end as well. Verify that the configured device is not configured as NAT IP. If NAT IPs are being used, then the configuration will need to be copied manually to the correct directory; C:\Program Files (x86)\lpagent\conf\lpagent.conf If the configuration is still not being pushed, create a support ticket with the below information: LPAgent log files pr

ThinkIn - Alerts and Widgets

Please find the material presented during the 2021 ThinkIn session on Alerts and Widgets attached to this article as well as the complete video recording from the session on Youtube via this link:https://www.youtube.com/watch?v=I2OvY72XtrYThe scripts mentioned during the presentation can also be downloaded from here.A few words on each of the scripts.pm_analyzer.pyThe primary purpose of the pm_analyzer.py script is to provide information about the performance of each livesearch. It is usually run interactively from the shell on systems experiencing performance issues with livesearches - widgets not updating, or alerts not firing as they should.Although the script will need to run for as long as the longest update cycle for any livesearch takes (which it doesn't inform about - yet) to provide complete information on all livesearches - on most systems the issues would probably become evident sooner as the performance would most likely be impacted by resource hogs that are updating freque

How to correct blank dashboard widgets?

A dashboard can go blank for various reasons,  check the following things to correct the blank dashboard before contacting LogPoint Support.Hit the query that is being used by the dashboard in the search bar and check if it has any matching logs. If you do not find any matching logs, then there is a chance that correct normalization packages are not in place for the corresponding normalization policy. If logs are shown and the dashboard is still blank,  check if the source devices are configured to the correct time zone from the device configuration settings. If  the widget is still empty even after correcting the timezone of a device,  try to add a “dummy dashboard“ or try to edit that specific dashboard. It will trigger the dashboard engine to regenerate the config and also helps to check if there is a problem with a single dashboard or in dashboards in general. If  the widget is still blank, create a support ticket with the below information: The query being used in the dashboard.
