NAME

       smokeping_examples - Examples of Smokeping configuration

OVERVIEW

       This document provides some examples of Smokeping configuration files.  All the examples
       can be found in the "examples" directory in the Smokeping documentation. Note that the DNS
       names in the examples are non-functional.

       Details of the syntax and all the variables are found in smokeping_config and in the
       documentation of the corresponding probe, if applicable.

       This manual is automatically generated from the Smokeping source code, specifically the
       Smokeping::Examples module.

DESCRIPTION

       Currently the examples differ only in the "Probes" and "Targets" sections. The other
       sections are taken from the "etc/config.dist" configuration template in the Smokeping
       distribution so that the example files are complete.

       If you would like to provide more examples, document the other sections or enhance the
       existing examples, please do so, preferably by sending the proposed changes to the
       smokeping-users mailing list.

   Example 1: config.simple
       Probe configuration
            *** Probes ***
            +FPing
            binary = /usr/bin/fping

       Probe explanation
           Here we have just one probe, fping, pinging four hosts.

           The fping probe is using the default parameters, some of them supplied from the
           Database section ("step" and "pings"), and some of them by the probe module.

       Target configuration
            *** Targets ***
            probe = FPing

            menu = Top
            title = Network Latency Grapher
            remark = Welcome to this SmokePing website.

            + mysite1
            menu = Site 1
            title = Hosts in Site 1

            ++ myhost1
            host = myhost1.mysite1.example
            ++ myhost2
            host = myhost2.mysite1.example

            + mysite2
            menu = Site 2
            title = Hosts in Site 2

            ++ myhost3
            host = myhost3.mysite2.example
            ++ myhost4
            host = myhost4.mysite2.example

       Target explanation
           The hosts are located in two sites of two hosts each, and the configuration has been
           divided to site sections ('+') and host subsections ('++') accordingly.

   Example 2: config.multiple-probes
       Probe configuration
            *** Probes ***
            + FPing
            binary = /usr/bin/fping
            packetsize = 1000

            + DNS
            binary = /usr/bin/dig
            lookup = name.example
            pings = 5
            step = 180

            + EchoPingHttp
            pings = 5
            url = /test-url

       Probe explanation
           Here we have three probes: FPing for the regular ICMP pings, DNS for name server
           latency measurement and EchoPingHttp for web servers.

           The FPing probe runs with the default parameters, except that the ICMP packet size is
           1000 bytes instead of the default 56 bytes.

           The DNS and EchoPingHttp probes have been configured to be a bit more gentle with the
           servers, as they only do 5 queries (pings) instead of the default 20 (or whatever is
           specified in the Database section). However, DNS queries are made more often: 5
           queries every 3 minutes instead of every 5 minutes.

       Target configuration
            *** Targets ***
            probe = FPing
            menu = Top
            title = Network Latency Grapher
            remark = Welcome to this SmokePing website.

            + network
            menu = Net latency
            title = Network latency (ICMP pings)

            ++ myhost1
            host = myhost1.example
            ++ myhost2
            host = myhost2.example

            + services
            menu = Service latency
            title = Service latency (DNS, HTTP)

            ++ DNS
            probe = DNS
            menu = DNS latency
            title = Service latency (DNS)

            +++ dns1
            host = dns1.example

            +++ dns2
            host = dns2.example

            ++ HTTP
            menu = HTTP latency
            title = Service latency (HTTP)

            +++ www1
            host = www1.example

            +++ www2
            host = www2.example

       Target explanation
           The target tree has been divided by the probe used. This does not have to be the case:
           every target (sub)section can use a different probe, and the same probe can be used in
           different parts of the config tree.

   Example 3: config.fping-instances
       Probe configuration
            *** Probes ***
            + FPing
            binary = /usr/bin/fping

            ++ FPingNormal
            offset = 0%

            ++ FPingLarge
            packetsize = 5000
            offset = 50%

       Probe explanation
           This example demonstrates the concept of probe instances. The FPingLarge and
           FPingNormal probes are independent of each other, they just use the same module,
           FPing. FPingNormal uses the default parameters, and so does FPingLarge except for the
           5 kilobyte packetsize. Both use the same fping binary, and its path is configured
           FPing top section.

           The 'offset' parameters make sure the probes don't run at the same time - FPingNormal
           is run every 'full' 5 minutes (eg. 8:00, 8:05, 8:10 and so on, in wallclock time)
           while FPingLarge is run halfway through these intervals (eg. 8:02:30, 8:07:30 etc.)

           The top FPing section does not define a probe in itself because it has subsections. If
           we really wanted to have one probe named "FPing", we could do so by making a
           subsection by that name.

       Target configuration
            *** Targets ***
            probe = FPingNormal
            menu = Top
            title = Network Latency Grapher
            remark = Welcome to this SmokePing website.

            + network
            menu = Net latency
            title = Network latency (ICMP pings)

            ++ myhost1
            menu = myhost1
            title = ICMP latency for myhost1

            +++ normal
            title = Normal packetsize (56 bytes)
            probe = FPingNormal
            host = myhost1.example

            +++ large
            title = Large packetsize (5000 bytes)
            probe = FPingLarge
            host = myhost1.example

            ++ myhost2
            menu = myhost2
            title = ICMP latency for myhost2

            +++ normal
            title = Normal packetsize (56 bytes)
            probe = FPingNormal
            host = myhost2.example

            +++ large
            title = Large packetsize (5000 bytes)
            probe = FPingLarge
            host = myhost2.example

       Target explanation
           The target section shows two host, myhost1.example and myhost2.example, being pinged
           with two differently sized ICMP packets. This time the tree is divided by the target
           host rather than the probe.

   Example 4: config.targetvars-with-Curl
       Probe configuration
            *** Probes ***
            + Curl
            # probe-specific variables
            binary = /usr/bin/curl
            step = 60

            # a default for this target-specific variable
            urlformat = http://%host%/

       Probe explanation
           This example explains the difference between probe- and target-specific variables. We
           use the Curl probe for this.

           Every probe supports at least some probe-specific variables. The values of these
           variables are common to all the targets of the probe, and they can only be configured
           in the Probes section. In this case, the probe-specific variables are "binary" and
           "step".

           Target-specific variables are supported by most probes, the most notable exception
           being the FPing probe and its derivatives. Target-specific variables can have
           different values for different targets. They can be configured in both Probes and
           Targets sections. The values assigned in the Probes section function become default
           values that can be overridden in the Targets section.

           The documentation of each probe states which of its variables are probe-specific and
           which are target-specific.

           In this case the "urlformat" variable is a target-specific one.  It is also quite
           uncommon, because it can contain a placeholder for the "host" variable in the Targets
           section. This is not a general feature, its usage is only limited to the "urlformat"
           variable and the "%host%" escape.

           (The reason why the FPing probe does not support target-specific variables is simply
           the fact that the fping program measures all its targets in one go, so they all have
           the same parameters. The other probes ping their targets one at a time.)

       Target configuration
            *** Targets ***
            probe = Curl
            menu = Top
            title = Network Latency Grapher
            remark = Welcome to this SmokePing website.

            + HTTP
            menu = http
            title = HTTP latency

            ++ myhost1
            menu = myhost1
            title = HTTP latency for myhost1
            host = myhost1.example

            ++ myhost2
            menu = myhost2
            title = HTTP latency for myhost2
            host = myhost2.example

            ++ myhost3
            menu = myhost3
            title = HTTP latency for myhost3 (port 8080!)
            host = myhost3.example
            urlformat = http://%host%:8080/

            + FTP
            menu = ftp
            title = FTP latency
            urlformat = ftp://%host%/

            ++ myhost1
            menu = myhost1
            title = FTP latency for myhost1
            host = myhost1.example

            ++ myhost2
            menu = myhost2
            title = FTP latency for myhost2
            host = myhost2.example

       Target explanation
           The target tree is divided into an HTTP branch and an FTP one.  The servers
           "myhost1.example" and "myhost2.example" are probed in both. The third server,
           "myhost3.example", only has an HTTP server, and it's in a non-standard port (8080).

           The "urlformat" variable is specified for the whole FTP branch as "ftp://%host%/". For
           the HTTP branch, the default from the Probes section is used, except for myhost3,
           which overrides it to tag the port number into the URL.

           The myhost3 assignment could just as well have included the hostname verbatim (ie.
           urlformat = http://myhost3.example:8080/) instead of using the %host% placeholder, but
           the host variable would still have been required (even though it wouldn't have been
           used for anything).

   Example 5: config.echoping
       Probe configuration
            *** Probes ***
            + FPing
            binary = /usr/bin/fping

            # these expect to find echoping in /usr/bin
            # if not, you'll have to specify the location separately for each probe
            # + EchoPing         # uses TCP or UDP echo (port 7)
            # + EchoPingDiscard  # uses TCP or UDP discard (port 9)
            # + EchoPingChargen  # uses TCP chargen (port 19)
            + EchoPingSmtp       # SMTP (25/tcp) for mail servers
            + EchoPingHttps      # HTTPS (443/tcp) for web servers
            + EchoPingHttp       # HTTP (80/tcp) for web servers and caches
            + EchoPingIcp        # ICP (3130/udp) for caches
            # these need at least echoping 6 with the corresponding plugins
            + EchoPingDNS        # DNS (53/udp or tcp) servers
            + EchoPingLDAP       # LDAP (389/tcp) servers
            + EchoPingWhois      # Whois (43/tcp) servers

       Probe explanation
           This example shows most of the echoping-derived probes in action.

       Target explanation
           All the servers are pinged both with ICMP (the FPing probe) and their respective
           echoping probe. The proxy server, www-cache, is probed with both HTTP requests and ICP
           requests for the same URL.
