Design new SNMP MIB
Hi all, I have a software package for which I need to report some status / configuration tables via SNMP/AgentX. Each table has a bunch of key=value pairs, where the list of keys could change in time (e.g. with new version), so I prefer not to hardcode them to the MIB directly. 1) My idea is to have some simple tables: One table should be read only for status reports: myDevice.tabStatus.varName.0 = STRING: "num_connections" myDevice.tabStatus.varName.1 = STRING: "mem_used" myDevice.tabStatus.varValue.0 = STRING: 123 myDevice.tabStatus.varValue.1 = STRING: 98765 The other read-write for setting system variables: myDevice.tabConfig.varName.0 = STRING: "max_connections" myDevice.tabConfig.varName.1 = STRING: "max_mem" myDevice.tabConfig.varValue.0 = STRING: 999 myDevice.tabConfig.varValue.1 = STRING: 9 So this is the basic. Drawback is it could be a bit of pain to do GET/ SET as I'll need to query the whole list of names from myDevice.tabStatus.varName, get the index of what I want and only then in another query get the actual variable. Or is there a shortcut? like: snmpget tabStatus.varValue.(tabStatus.varName=="mem_used") ... I doubt so. Another thing is that I'll need to return all varValue.X as STRINGs even if some of them are actually integers. Or can I have each index in a table of a different type? 2) Now I thought it would be nice to have some well known and often used status and config variables accessible directly through MIB, e.g. myDevice.statusVar.num_connections = INTEGER: 123 the drawback being that the names are hardcoded in the MIB which may become obsolete once we add new variables. OTOH I could specify the variable types (some are STRING, some are INTs). 3) Or perhaps all of them in a similar fashion to what 'extend' does in snmpd.conf, i.e. "myDevice.statusVar."num_connections" = INTEGER: 123" >From the user perspective it looks cool but is it a clean way to do from the SNMP/MIB point? Plus - can I list all variables in such case? And again I'll probably have to work without types, i.e. all-STRINGs. What would you recommend? Is is OK to have one variable accessible in two ways, i.e. via both #1 and #2 or #3? I'm sure #1 is by far the most flexible while the others are more convenient. So my preference would be #1 plus either #2 or #3. BTW How should I assign OID to my MIB? Do I need to apply for an Enterprise ID with IANA? Is there an OID reserved for testing / development? I don't know yet much about designing and writing MIBs so I'm seeking some advices here. Any thoughts and pointers are highly appreciated! Thanks Michal - Using Tomcat but need to do more?

Well, that does sound like a generic statistics table. You can't change the number of *columns* dynamically, but you can certainly add new rows (corresponding to new statistics). So you'd probably have three columns in this table (plus the external genServerIndex): * genStatisticsIndex - to distinguish between multiple statistics relating to the same server * genStatisticsDescr - a textual description of what this statistic reports * genStatisticsValue - the value for this statistics So you might have a table such as: 1 1"# Silly Questions received"23 1 2"# Sarcastic Answers"22 1 3"# Clearly phrased Questions" 3 2 2"# Silly Questions received" 17 2 3"# Patient Answers"18 Note that a given "genStatisticsIndex" value can refer to two different statistic for two different servers.

FW: Re: How can I extend a MIB with a subagentX
To be more detailed, if I have a generic MIB with the following tables: - genServerTable with the index genServerIndex, and columns 'name', 'ipAddress' and 'portNumber' - genDBServerTable with the index genServerIndex and genDBServerIndex, and column 'dbName' - genStateTable with the index genServerIndex and genStateIndex, and the column 'State' - genStatisticsTable with the index genServerIndex and genStatisticsIndex : statistics here are specific to each server Is there a generic way to create the genStatisticsTable with columns that can be added dynamically by a sub agent? Is is feasible?

Hi, Now I tried installing Net-SNMP-5.3.1 on Solaris9 Configure command was used as follows ./configure --prefix=/net/tcsnas01/vol/nxqa/qa/local/net-snmp_sol --enable-ipv6 When running configure the following error repeated ... checking ipv6 stack type... "unknown, no" ... After configure was through I checked configure.log and found following ... configure:12581: checking ipv6 stack type conftest.c:43:45: /usr/local/v6/include/sys/types.h: No such file or directory conftest.c:43:22: features.h: No such file or directory configure:12755: result: "unknown, no" ... In fact I did not find directory v6 under /usr/local let alone the file. I was wondering why this is so. As of now I suspect that I have a runtime only IPv6 environment And My gcc is not fully loaded and does not supports compiling IPv6 code because of which I do not have v6 directory under /usr/local Please suggest a way out...

try to remove row in ifTable
I try to remove some rows in the ifTable, the loopback interface and some interface use for internal communication. I program the snmpd.conf with these lines: com2sec sec1 default public group gp1 v1 sec1 group gp1 v2c sec1 view vn1 included .1 view vn1 excluded ifEntry.1.1 0x3:0xf9 But this only remove the index field of the lo interface. I found a way by repeating the line with the second digit incrementing by one: view vn1 excluded ifEntry.1.1 view vn1 excluded ifEntry.2.1 view vn1 excluded ifEntry.3.1 view vn1 excluded ifEntry.4.1 ... but we have 22 items in each ifEntry and for interface to remove.

Re: How can I extend a MIB with a subagentX
Hi, Let's detail, for example, 3 different applications i want to monitor (in reality, I have almost 60) For the 3 applications, we have the following metrics(this is an overview): Application 1: - Number of SQL updates executed - Number of SQL updates per second - Number of failed operations - State Application 2: - Number of messages received - Number of messages processed - Number of messages processed by second - Number of pending messages - State Application 3: - Number of threads - Number of active threads - Number of operations processed by thread - State Each application can be launched on several databases and can be launched multiple times (for performance reasons) on each database. Let's imagine I have a MIB containing a list of servers (by using a SEQUENCE). My problems are: - How can I define specific caracteristics (different for each server) with a generic MIB? - If, in the manager console, I have four instances of the same server: - Application1 on database DB1 (First instance) - Application1 on database DB1 (Second instance on the same database for performance reason) - Application1 on database DB2 (third instance) - Application1 on database DB3 (Fourth instance) All these servers are subagent (AgentX).

Re: Problem on 64 bit machine
Thanks Dave. Size of long is 8.

Note that (for historical reasons), integer values are held internally as "long" rather than "int".This is so pervasive that it would be extremely difficult to change now. I believe that what's been done to address this problem, is to mask off the bottom 32-bits of all integer values (other than Counter64) - probably when building the PDU. You could either tweak your library code to do the same, or do an equivalent masking when setting the values.

Re: Problem on 64 bit machine
I have my own mib, where the objects are defined to have SYNTAX as Integer32. When I am trying to set the value of the object on a 64 bit machine, the "requests" variable passed in the table_handler function has requests->requestvb->val_len assigned as 8. I want to know why this value is 8 and not 4. (sizeof(int) gives 4 on that machine)? Also, where this value gets set by net-snmp?

'val_len' is a parameter to the UCD v4-style module API, so it will be set individually for each different MIB object. Some of the utility routines may set this to a default value, but it's quite common for particular MIB object implementations to reset it. More details needed.

And if that still doesn't work, have a look in 'config.log' for where configure tests for the presence of the IPv6 stack. If it's not detecting this stack correctly, then this problem needs to be fixed before proceeding.

You can suppress these messages at run-time, by starting the agent using snmpd -m "" . You can turn these messages off completely (and reduce the size of the libraries slightly) by running configure using "--disable-mib-loading" and re-compiling.

Frustrated with enabling Ipv6 support on Solaris 9
Hi, I am frustrated with enabling Ipv6 support on Solaris 9. The software versions I am using are as follows 1) Net-SNMP 5.1.3.1 2) GCC 3.3 3) Solaris 5.9 The configure command used as follows ./configure --prefix=/net/tcsnas01/vol/nxqa/qa/local/net-snmp_sol --enable-ipv6 When the configure is running the I see following message on console ... Ipv6 stack ... [unknown, no] ... For the IPv6 enabled host I have checked that IPv6 support is up and running using following tools from another Ipv6 enabled host 1) ping (works ok) 2) telnet 13 (works ok) 3) netstat -a (shows IPv6 connections between the hosts) I proceeded with the installation but I do not have support for IPv6 directives that I need to use in snmpd.conf The output of command "./snmpd -H" does not shows "rocommunity6 and rwcommunity6". Of course any further attempts for starting agent with udp6 yields errors and none of the snmpget command fetches replies from the agent. IPv6 part is ok though. Please provide help/pointers to enable IPv6 support on Solaris 9. Sincerely, Rahul K - Using Tomcat but need to do more? Need to support web services, security?

What do you mean by "restarts the snmpd"? Do you mean kill off the currently running agent and start a fresh one? 'Cos I don't think that will work - if nothing else, it's the parent of the script that's trying to kill it. I'm not sure that patricide is safe! Why don't you just signal to the currently running agent to re-read its configuration? The agent is already set up to do that - simply send it a HUP signal. Dave - Using Tomcat but need to do more?
