VINYLTOP(1) General Commands Manual VINYLTOP(1) NAME vinyltop - Vinyl Cache log entry real-time view SYNOPSIS vinyltop [-1] [-b] [-c] [-C] [-d] [-E] [-f] [-g <session|request|vxid|raw>] [-h] [-i <taglist>] [-I <[taglist:]regex>] [-L <limit>] [-n <workdir>] [-p <period>] [-Q <file>] [-q <query>] [-r <filename>] [-t <seconds|off>] [-T <seconds>] [-x <taglist>] [-X <[taglist:]regex>] [-V] DESCRIPTION The vinyltop utility reads vinyld(1) shared memory logs and presents a con- tinuously updated list of the most commonly occurring log entries. With suitable filtering using the -I, -i, -X and -x options, it can be used to display a ranking of requested documents, clients, user agents, or any other information which is recorded in the log. The following options are available: -1 Instead of a continuously updated display, print the statistics once and exit. Implies -d. -b Only display transactions and log records coming from backend commu- nication. -c Only display transactions and log records coming from client commu- nication. -C Do all regular expression and string matching caseless. -d Process log records at the head of the log. -E Display ESI transactions and other types of sub-requests. This im- plies the -c option and includes other client transactions. -f Sort and group only on the first field of each log entry. For log entries in the form prefix: value it is the prefix without the colon that is sorted and grouped. This is useful when displaying e.g. Re- qStart entries, where the first field is the client IP address. -g <session|request|vxid|raw> The grouping of the log records. The default is to group by vxid. -h Print program usage and exit -i <taglist> Include log records of these tags in output. Taglist is a comma-sep- arated list of tag globs. Multiple -i options may be given. If a tag include option is the first of any tag selection options, all tags are first marked excluded. -I <[taglist:]regex> Include by regex matching. Output only records matching taglist and regular expression. Applies to any tag if taglist is absent. Multi- ple -I options may be given. If a tag include option is the first of any tag selection options, all tags are first marked excluded. -L <limit> Sets the upper limit of incomplete transactions kept before the old- est transaction is force completed. A warning record is synthesized when this happens. This setting keeps an upper bound on the memory usage of running queries. Defaults to 1000 transactions. -n <workdir> Specify the vinyl working directory of the instance to attach to. See vinyld(1) -n option documentation for additional information and defaults. -p <period> Specified the number of seconds to measure over, the default is 60 seconds. The first number in the list is the average number of re- quests seen over this time period. This option has no effect if -1 option is also used. -Q <file> Specifies the file containing the VSL query to use. When multiple -Q or -q options are specified, all queries are considered as if the 'or' operator was used to combine them. -q <query> Specifies the VSL query to use. When multiple -q or -Q options are specified, all queries are considered as if the 'or' operator was used to combine them. -r <filename> Read log in binary file format from this file. The file can be cre- ated with vinyllog -w filename. If the filename is -, logs are read from the standard input. and cannot work as a daemon. -t <seconds|off> Timeout before returning error on initial VSM connection. If set the VSM connection is retried every 0.5 seconds for this many seconds. If zero the connection is attempted only once and will fail immedi- ately if unsuccessful. If set to "off", the connection will not fail, allowing the utility to start and wait indefinitely for the vinyld instance to appear. Defaults to 5 seconds. -T <seconds> Sets the transaction timeout in seconds. This defines the maximum number of seconds elapsed between a Begin tag and the End tag. If the timeout expires, a warning record is synthesized and the trans- action is force completed. Defaults to 120 seconds. -x <taglist> Exclude log records of these tags in output. Taglist is a comma-sep- arated list of tag globs. Multiple -x options may be given. -X <[taglist:]regex> Exclude by regex matching. Do not output records matching taglist and regular expression. Applies to any tag if taglist is absent. Multiple -X options may be given. -V Print version information and exit. --optstring Print the optstring parameter to getopt(3) to help writing wrapper scripts.
