<div role="presentation" style="margin-top: 1em; margin-bottom: 1em;"><code>stats-exporter</code>: Added two new sources,
<code>stats-exporter()</code> and <code>stats-exporter-dont-log()</code>, which directly serve the output of
<code>syslog-ng-ctl stats</code> and <code>syslog-ng-ctl query</code> to a http scraper. The only difference is that
<code>stats-exporter-dont-log()</code> suppresses log messages from incoming scraper requests, ensuring no messages appear in the log path. Meanwhile,
<code>stats-exporter()</code> logs unparsed messages, storing incoming scraper HTTP requests in the
<code>MSG</code> field.</div>
<div role="presentation" style="margin-top: 1em; margin-bottom: 1em;">Example usage for a Prometheus Scraper which logs the HTTP request of the scraper to /var/log/scraper.log:</div>
<pre role="presentation"><div style="font-family: Aptos, "Aptos_EmbeddedFont", "Aptos_MSFontService", Calibri, Helvetica, sans-serif;"><code>@version: 4.9
@include "scl.conf"
source s_prometheus_stat {
stats-exporter(
ip("0.0.0.0")
port(8080)
stat-type("query")
stat-query("*")
scrape-freq-limit(30)
single-instance(yes)
);
};
log {
source(s_prometheus_stat);
destination { file(/var/log/scraper.log); };
};
</code></div></pre>
<div role="presentation" style="margin-top: 1em; margin-bottom: 1em;">Example usage for a generic HTTP Scraper which sends e.g. the
<code>GET /stats HTTP/1.1</code> HTTP request to get statistics of syslog-ng, do not want to log or further process the HTTP requests in the log pipe, and needs the response in CSV format:</div>
<pre role="presentation"><div style="font-family: Aptos, "Aptos_EmbeddedFont", "Aptos_MSFontService", Calibri, Helvetica, sans-serif;"><code>@version: 4.9
@include "scl.conf"
source s_scraper_stat {
stats-exporter-dont-log(
ip("0.0.0.0")
port(8080)
stat-type("stats")
stat-format("csv")
scrape-pattern("GET /stats*")
scrape-freq-limit(30)
single-instance(yes)
);
};
log {
source(s_scraper_stat);
};
</code></div></pre>
<div role="presentation" style="margin-top: 1em; margin-bottom: 1em;">Note: A destination is not required for this to work; the
<code>stats-exporter()</code> source will respond to the scraper regardless of whether a destination is present in the log path.</div>
<div role="presentation" style="margin-top: 1em; margin-bottom: 1em;">Available options:</div>
<div role="presentation" style="margin-top: 1em; margin-bottom: 1em;"><code>stat-type(string)</code> -
<code>query</code> or <code>stats</code>, just like for the <code>syslog-ng-ctl</code> command line tool, see there for the details<br>
<code>stat-query(string)</code> - the query regex string that can be used to filter the output of a
<code>query</code> type request<br>
<code>stat-format(string)</code> - the output format of the given stats request, like the
<code>-m</code> option of the <code>syslog-ng-ctl</code> command line tool<br>
<code>scrape-pattern(string)</code> – the pattern used to match the HTTP header of incoming scraping requests. A stat response will be generated and sent only if the header matches the pattern string<br>
<code>scrape-freq-limit(non-negative-int)</code> - limits the frequency of repeated scraper requests to the specified number of seconds. Any repeated request within this period will be ignored. A value of 0 means no limit<br>
<code>single-instance(yes/no)</code> - if set to <code>yes</code> only one scraper connection and request will be allowed at once<br>

<div role="presentation" style="margin-top: 1em; margin-bottom: 1em;">|Accepted values:| legacy | inotify | poll | system |</div>
<div role="presentation" style="margin-top: 1em; margin-bottom: 1em;">This option controls how syslog-ng will follow file changes.<br>
The default <code>legacy</code> mode preserves the pre-4.9 version file follow-mode behavior of syslog-ng, which is based on the value of follow-freq().<br>
The <code>poll</code> value forces syslog-ng to poll for file changes at the interval specified by the monitor-freq() option, even if a more efficient method (such as
<code>inotify</code> or <code>kqueue</code>) is available.<br>
If <code>inotify</code> is selected and supported by the platform, syslog-ng uses it to detect changes in source files. This is the most efficient and least resource-consuming option available on Linux for regular files.<br>
The <code>system</code> value will use system poll methods (via ivykis) like <code>
port-timer</code> <code>port</code> <code>dev_poll</code> <code>epoll-timerfd</code>
<code>epoll</code> <code>kqueue</code> <code>ppoll</code> <code>poll</code> and <code>
uring</code>. For more information about how to control the system polling methods used, see
