This example starts a process that prints the C:\PS-Test\MyFile.txt file. Start-Process -FilePath "sort.exe" Example 2: Print a text file The command usesĪll of the default values, including the default window style, working folder, and credentials. This example starts a process that uses the Sort.exe file in the current folder.
Examples Example 1: Start a process that uses default values
Starting the process in a new window, or using alternate credentials. You can use the parameters of Start-Process to specify options, such as loading a user profile, Start-Process starts the program that is associated with the file, similar to the Invoke-Item That can be opened by using a program on the computer. To specify the program that runs in the process, enter an executable file or script file, or a file Start-Process creates a new process that inherits all the environment variables that are defined The Start-Process cmdlet starts one or more processes on the local computer. When iterating on getting this set up correctly, it is necessary to reset/delete the template, indices, pipeline and Kibana's field cache-discovering all of these was the main impediment for me getting the field to be interpreted by Kibana as the correct type, and the probable cause of the apparent voodoo directions above.Starts one or more processes on the local computer. This prompts with a warning that it “resets the popularity count of each field”, but more importantly it also discards the previously cached type information for each field, which is what we need. The final step is to refresh the field list in Kibana, from the Management tab. Since I don't care about the existing history I just delete all the existing indices: curl -XDELETE " Restart Filebeat and you will see it recreating the template and index in the journalctl log: sudo service filebeat start You can verify the result of the above by examining the resulting JSON: sudo filebeat export templateĭelete the existing template from Elasticsearch (again, this seems like something that's meant to be overwritten but in my experience was not): curl -XDELETE " You also need a new index, which by default is created every day. Tell Filebeat to regenerate its index template (effectively just converting this YAML file to JSON): sudo filebeat setup -template Follow these steps to add the field type, beginning with stopping the Filebeat service: sudo service filebeat stopĪdd the following magic to /etc/filebeat/filebeat.yml: : "filebeat"Īdd the field definition to /etc/filebeat/fields.yml, under the response.status_code definition (around line 1137, and be wary of indentation): - name: response.timeĭescription: Time to process the request, in microseconds This field,, is made-up, and if we stop at this point it will not have any data type associated with it this causes Elasticsearch to import it as text by default, which means we can't do useful things like compute percentiles in Kibana. This is pretty simple just edit the /usr/share/filebeat/module/apache/access/ingest/default.json file, which begins with: in the ingest pipeline. Now we need Filebeat to parse this field from the log line.
Restart Apache and tail /var/log/apache2/access.log to check that this is working. In my case I added \"%V\" to the end of the combined log format directive, in order to have it output the canonical host name. My goal here is to add a url.domain field, so that I can distinguish requests that arrive at different domains.įirst of all, edit /etc/apache2/nf to add an extra field to the LogFormat. By default Filebeat provides a url.original field from the access logs, which does not include the host portion of the URL, only the path. My web server hosts pages for a few domains, using Apache's VirtualHosts. Response time per request, in microseconds ( ) Ingesting an extra field.Barclay Howe's blog was very useful in figuring this out. This did not turn out to be straightforward-while all the required plumbing and customisation is already supported, the process of getting fields to be interpreted with the correct data type is convoluted and badly documented. This time I add a couple of custom fields extracted from the log and ingested into Elasticsearch, suitable for monitoring in Kibana. In the previous post I wrote up my setup of Filebeat and AWS Elasticsearch to monitor Apache logs.
