+ - intel_pmu
+ The intel_pmu plugin reads performance counters provided by the Linux
+ kernel perf interface. The plugin uses jevents library to resolve named
+ events to perf events and access perf interface.
+
- intel_rdt
The intel_rdt plugin collects information provided by monitoring features
of Intel Resource Director Technology (Intel(R) RDT) like Cache Monitoring
- netapp
Plugin to query performance values from a NetApp storage system using the
- “Manage ONTAP” SDK provided by NetApp.
+ “Manage ONTAP” SDK provided by NetApp.
- netlink
Very detailed Linux network interface and routing statistics. You can get
plugin of choice for that.
- nfs
- NFS Procedures: Which NFS command were called how often. Only NFSv2 and
- NFSv3 right now.
+ NFS Procedures: Which NFS command were called how often.
- nginx
Collects statistics from `nginx' (speak: engine X), a HTTP and mail
For querying iptables counters.
<http://netfilter.org/>
+ * libjevents (optional)
+ The jevents library is used by the `intel_pmu' plugin to access the Linux
+ kernel perf interface.
+ Note: the library should be build with -fPIC flag to be linked with
+ intel_pmu shared object correctly.
+ <https://github.com/andikleen/pmu-tools>
+
* libjvm (optional)
Library that encapsulates the `Java Virtual Machine' (JVM). This library is
used by the `java' plugin to execute Java bytecode.

+/**
+ * There is two main kinds of OpenVPN status file:
+ * - for 'single' mode (point-to-point or client mode)
+ * - for 'multi' mode (server with multiple clients)
+ *
+ * For 'multi' there is 3 versions of status file format:
+ * - version 1 - First version of status file: without line type tokens,
+ * comma delimited for easy machine parsing. Currently used by default.
+ * Added in openvpn-2.0-beta3.
+ * - version 2 - with line type tokens, with 'HEADER' line type, uses comma
+ * as a delimiter.
+ * Added in openvpn-2.0-beta15.
+ * - version 3 - The only difference from version 2 is delimiter: in version 3
+ * tabs are used instead of commas. Set of fields is the same.
+ * Added in openvpn-2.1_rc14.
+ *
+ * For versions 2/3 there may be different sets of fields in different
+ * OpenVPN versions.
+ *
+ * Versions 2.0, 2.1, 2.2:
+ * Common Name,Real Address,Virtual Address,
+ * Bytes Received,Bytes Sent,Connected Since,Connected Since (time_t)
+ *
+ * Version 2.3:
+ * Common Name,Real Address,Virtual Address,
+ * Bytes Received,Bytes Sent,Connected Since,Connected Since (time_t),Username
+ *
+ * Version 2.4:
+ * Common Name,Real Address,Virtual Address,Virtual IPv6 Address,
+ * Bytes Received,Bytes Sent,Connected Since,Connected Since (time_t),Username,
+ * Client ID,Peer ID
+ *
+ * Current Collectd code tries to handle changes in this field set,
+ * if they are backward-compatible.
