Hi everyone,

We recently upgraded our environment to the latest version (25.4). Since the update, we've noticed that a new column has been added to the login-audit.csv file.

We have already updated the headers to accommodate this change for both historical and future data. However, we are running into an issue with the files generated on the day of the upgrade. It seems there is a conflict between the data before and after the updrade , resulting in null values.

Has anyone else encountered this problem?

Thanks in advance!

Best regards,

Can this plug-in be used in a high available environment to retrieve all instances of one log file?
We want to retrieve the design_errors.csv log from all 3 of our servers to display in one place.

Hi, I want to filter rows from login-audit.csv based on the usernames I have. Any idea about that.

I could use an example or better documentation on how to use this plug in. I am looking to query the tomcat-stdOut.log for ERRORS, parse the information, store in a database table, and display in a grid for our developers to monitor.

Hello! We use this plugin on a very regular basis to scrape and maintain the history of certain logs so we can determine the health of our environment based upon internally-developed tools. We'd like to extend this to the process execution engines logs. However, those logs have dynamic names which include a date and a timestamp (for better or worse, we can argue that elsewhere...).

Would it be possible to enhance this plugin to support a wildcard character in the filename itself? Alternatively, would it be possible to add a function that can get a directory listing of *.csv/*.log file names matching a search? For example, I'd like all file names with "execution_by_category" in the name.

It's possible to automate the scraping of process execution logs with no modifications to the plugin, but it takes a bit of brute force to determine the file names, which makes it quite a cumbersome to do at scale across dozens of engines / files.

Does this not work for the audit/design_objects.csv log? The rows return a null and the totalCount is -1

RE: Log Reader

Alberto Cortés — Tue, 03 Dec 2024 15:54:39 GMT

In the readcsvlog function and all its variants, the row results are returned by concatenating each field with the variable private static final String SEPARATOR, whose value is a comma. When concatenating values that contain a comma, there is no way to parse the results. If it is not possible to return the rows as an array of strings (with each field as an element), could an extension be made to allow passing the output separator value?

Anyone run into this error? I'm simply passing in pagingInfo to the recordTypeSource function through use of the a!query() function.

Expression evaluation error at function 'systemlogsrecordtypesource' [line 7]: The passed parameter(s) are of the wrong type. Received the type com.appiancorp.common.xml.JaxbConversionException: JAXB failure trying to convert typed value TypedValue[it=1474,v={TypedValue[it=1478,v=<null>],TypedValue[it=1154,v=<null>],{1,101,<null>}}] to java class com.appiancorp.common.query.Query.

Hi, teams,

I am trying to get a day's worth of rdbms-audit logs.
However, I have tried the following expression, but could not get the logs that have been evacuated.
Any help would be appreciated. Thanks in advance.

Log format: rdbms-audit.log.yyyy-mm-dd.*

readlogpaging(
logPath: "audit\rdbms\rdbms-audit.log." & tostring(year(today())) & "-" & substitute( padleft(tostring(month(today())), 2), " ", "0" ) & "-" & substitute( padleft(tostring(day(today())), 2) & "." & tostring(pv!LogCounter), " ", "0" ),
startIndex: 1,
batchSize: - 1
).rows

RE: Log Reader

Sayed Hashimi — Thu, 27 Jun 2024 15:10:49 GMT

We are trying to consume the rdbms-audit logs. We are using the function taillogpaging(). If you pass a timestampStop to this function, it does not return any data. The timestamp format in the rdbms-audit log is yyyymmdd hh:mm:ss.

We also use the taillogpaging() while consuming the tomcat-access logs and that log has a timestamp format of yyyy-mm-dd hh:mm:ss. This seems to work.

Any suggestions?

Hi Team,

I am trying to get sites usage data from logs by using readcsvlog function but just getting headers and null for rows. Total count is coming as -1. Tried using readcsvlogpaging and readcsvlogpagingwithheaders functions too but that also didn't seem to work.

Not sure if there is anything to do with size of file as that log file is more than 6 mb. I am able to get data for other log files. Currently working on 24.2 version.

PFA code snippet and output.

Any help would be appreciated. Thanks in advance.
