(like "ltm. is one of: 'set' 'incr' 'get' 'remove' 'dump' 'drop_row' F5-BIGIP-LOCAL-MIB::ltmServerSslMaxActiveHandshake."/Common/crypto-client-default-serverssl" = Gauge32: 0į5-BIGIP-LOCAL-MIB::ltmServerSslStatHandshakeFailures."/Common/serverssl" = Counter64: 0Ĭounters only increase, but gauge could increase or decrease (it allows you to set a negative increment). String is a text, and the difference between counter and gauge is bit sutil (similar to counter and gauge difference in SNMP). The maximum length of the line (the sum of all columns) is 4032 bytes.Counter, Gauge and String are just measure types, not a format types. It is very dangerous to add too many columns to a particular table. Istats drop_column "keyspace table_2 string column_3" # removes a column from all rows in a particular table Istats remove "table_2 row_1 string column_2" # sets the value to default (does not actually remove anything from the table) Straightforward so far, but now we get to those other commands, which should make a lot more sense now that we know what keyspace/row/column all mean in this context. Istats set "table_2 row_1 string column_3" "aliqua"Īnd to pull that back out we would use: istats get "table_1 row_2 string column_2" Istats set "table_2 row_1 string column_2" "dolore" Istats set "table_2 row_1 string column_1" "amet" Istats set "table_1 row_2 string column_2" "magna" Istats set "table_1 row_2 string column_1" "dolor" Istats set "table_1 row_1 string column_2" "ipsum" We would: istats set "table_1 row_1 string column_1" "lorem" So to create iStats tables that (in our heads) look like this: # However, I've been poking around at iStats lately and (through trial and error) I think I can explain how this command actually works.īasically, setting an iStat goes like this: istats set " " Recommend looking at the following for more info: Introduction to iStatsĭocumentation here is atrocious. test.istat : nextBlockId=704, last update at 10:45:02 You can then use istats get -s test.istat "uri /12345 counter Requests" or istats incr -s test.istat "uri /12345 counter Requests" 1 which will only read and update the local file and not have any effect on the BIG-IP's actual iStats.Ī good option is to dump the lot using something like istats dump -s test.istat which would look like the following. istats set -s test.istat "uri /12345 counter Requests" 1 will write the file test.istat and create the record Requests as above. Or, if you don't care about that and just want the last update time, you can group by the table name: SELECT o.name as TableName, max (istats.lastuserupdate) from sys.dmdbindexusagestats istats inner join sys.objects o on o.objectid istats.objectid group by o.name. The -s is simply a way to write iStats to a file for testing e.g. istats set "uri /12345 counter Requests would set an iStat named Requests under the class uri, object named /12345 and a type of a counter ![]() ![]() ![]() Start with key which is made up of class, object, measure type ( counter, gauge, string, text, signed, unsigned, bin, dec, hex, timestamp, timeval, uinthex), and measure name to be separated by whitespace and enclosed in double quotes.Į.g. This is a CLI command equivilant to the iRule ISTAT commands (see here for more info DevCentral Wiki - iRules ISTAT). I had ipression that those can be set without using value (like automatically place current time at the moment key is created in value) but it seems not be the case.Piotr What is difference between timestamp and timeval. " - what is keyspace and column? If possible some example of key using all above elements and multiple columnsIs there any description what can be stored in types: 'text' 'signed' 'unsigned' 'bin' 'dec' 'hex' 'timestamp' 'timeval' 'uinthex'And how those behave in relation to value used. I wonder if there are is any info how to use operations like drop_row, drop_colum, clear_rowĭescription "keyspace. Must be specified for 'set' and 'incr', and must be an integer for 'incr' 'dec' 'hex' 'timestamp' 'timeval' 'uinthex' Is one of: 'counter' 'gauge' 'string' 'text' 'signed' 'unsigned' 'bin' (like "ltm.pool /Common/mypool counter mystat") Is one of: 'set' 'incr' 'get' 'remove' 'dump' 'drop_row' Here is help displayed by cli istats command: Usage: istats
