snmptools

1.0.0.0
first version

1.0.0.1
decimal separator forced to '.'

fixed : wait for snmpextensioninit to enumerate objects

1.0.0.3
fixed : snmp walk returns the right status when no more objects to walk

1.0.0.4
added : more debug outputs
fixed : oid:=nil in snmpextensionquery

todo : act a "proxy"  & get remote perf objects... ?
todo : handle multi oid in one request

1.0.0.5
added : hardcoded oid's based on ini files

1.0.0.6
fixed : in counters.ini, will not send default instance value if specified instance does not exists

todo : implement snmp set
todo : manage snmpwalk with ini file

1.0.0.7
modified : use VarIsFloat to check type of returned value
added : will manage all local separator decimal (and not only the ",")

1.0.0.8
added : enable counter flags in the ini file to get a specific counter when 2 same counternames exist
if no flag specified, will not use perf counters with PERF_DISPLAY_NOSHOW flag (example of % disk time)

1.0.0.9
added : can compile with FPC
added : cross compiled with fpc for x86_64 / win64 (only the exec oid flag works for now)

2.0.0.1
modified : switched to pdh api (via jwapdh) for x64 compatibility (does not work yet)
modified : switch jwasnmp headers for higher compatibility
modified : works only with a counters.ini file now
modified : counters are formatted now by default
modified : better memory mgmt
added : snmp getnext support
added : flag="raw" under counter section will return raw instead of formatted counter

2.0.0.2
fixed : a bug with instances='' 

2.0.0.3
added : SnmpExtensionQueryEx implementation (to support snmp v2c request types)

2.0.0.4
fixed : "SnmpExtensionQueryEx: List index out of bounds" on last oid in getnext request

2.0.0.5
added : flag="hi" or "lo" supported to retrieve the hi or lo part of an int64 value
added : multiple flags ok like flag=raw,hi (will help getting dword simple counter values under win64)
added : a reg file to run the snmptools 32bits edition under win64
added : flag="norefresh" to skip first PdhCollectQueryData (takes 1 sec)

2.0.0.6
modified : will use PDH_FMT_DOUBLE if counter type=PERF_SIZE_LARGE else will use PDH_FMT_LONG
todo : implement traps

2.0.0.7
added : SnmpExtensionTrap support (registry key "traps" = "c:\traps.ini" in registry). message=script output
todo : manage request with pVarBindList.len >1

2.0.0.8
added : support for pVarBindList.len >1 (multiple oid in one request like SPINE) 
fixed : "if size>0 then" in makepath function (result of PdhMakeCounterPathA is not consistent)
fixed : "VarIsFloat" dropped in formatvalue function (would not work on some o.s and thus would not convert the ",")
added : new flags "swap64" (hi<->lo), "cdbl" (int64 to double)
modified : will send asn_counter64 instead of asn_integer32 when value>high(integer) (snmp v2 and up)
fixed : win64 agent will use PDH_FMT_LARGE instead of PDH_FMT_DOUBLE (what about floats then?)
modified : win64 agent will always return PdhFmtCounterValue.largeValue
fixed : formatted perf_type_number counters tested oki in win64 mode (what about perf_type_counter?)

2.0.0.9
fixed : SnmpExtensionTrap will send all traps in one single snmp message
modified : will send a message (made of one or multi traps) only if at least one trap contains data
added : trap_delay registry key (default=15000ms) to modify time between 2 runs

2.0.0.10
modified : up to 65535 counters in ini file

2.0.0.11
added : can choose agent OID thru "OID" regsitry key

2.0.0.12
fixed : "\" characters in the instance name is now handled correctly
todo : comparemem to oidprefix in getrequest

2.0.0.13
fixed : memory allocation error on PdhGetCounterInfo
fixed : will not read all oid's in each snmpgetnext but only up to the requested oid

2.0.0.14
fixed : bug in tinifile.readsections (buffer limited to 16384 extended to 16384*2)
todo : multiply and div flags

2.0.0.15
added : new reg key "collect_delay"(dword) to control the time between 2 perf snapshot (default=1000ms)
modified : PDH_FMT_NOSCALE added to PdhGetFormattedCounterValue / PdhCalculateCounterFromRawValue
fixed : raw counters (flag="raw") fully supported thru PdhCalculateCounterFromRawValue
added : new flag "round" to round a float number to integer (not sure all snmp clients like float in strings)
modified : asn_counter64 does not work for now, back to ASN_OCTETSTRING for 64bits values

2.0.0.16
modified : will use by default PDH_FMT_DOUBLE in win32 mode
todo : look at ExpandPath (for wildcards) and Scales

2.0.0.17
modified : GetRawValue/GetFormattedValue will return null not 'null' when counter has null value
