SNMP4J Agent and Net-SNMP "client" -

-

i'm still learning snmp, gentle please.

i did agent snmp4j , seems working, have scalar should register how time has passed since agent started.

i have agent, see value of scalar net-snmp.

the problem is, when start agent set scalar systemuptime 0, try update systemuptime everytime tries check net-snmp value doesnt change.

how can agent update systemuptime everytime tries access it? have method moscalar getsystemuptime since updates systemuptime before returning , thought job, not working.

what u guys sugest?

edit ( agent code, ive taken off of mandatory methods short thing bit )

public class agent extends baseagent {     // not needed useful of course     static {         logfactory.setlogfactory(new log4jlogfactory());     }         static long starttime=0;     private string address;        static  oid oid= new oid(".1.3.6.1.4.1.1.1.0");        public static moscalar sysuptime;        private static mofactory mofactory =      defaultmofactory.getinstance();     public agent(string address) throws ioexception {          // these files not exist , not used has specified         // read snmp4j docs more info         super(new file("conf.agent"), new file("bootcounter.agent"),                 new commandprocessor(                         new octetstring(mpv3.createlocalengineid())));         this.address = address;     }       /**      * clients can register mo need      */     public void registermanagedobject(managedobject mo) {         try {             server.register(mo, null);                         system.out.println("mib filled!");         } catch (duplicateregistrationexception ex) {             throw new runtimeexception(ex);         }     }       /**      * start method invokes initialization methods needed      * start agent      * @throws ioexception      */     public void start() throws ioexception {          init();         // method reads old config file , causes         // unexpected behavior.         // loadconfig(importmodes.replace_create);          addshutdownhook();         getserver().addcontext(new octetstring("public"));         finishinit();         run();         sendcoldstartnotification();     }        protected void unregistermanagedobjects() {         // here should unregister objects registered...     }      /**      * table of community strings configured in snmp      * engine's local configuration datastore (lcd).      *       * configure one, "public".      */     protected void addcommunities(snmpcommunitymib communitymib) {         variable[] com2sec = new variable[] {                  new octetstring("public"), // community name                 new octetstring("cpublic"), // security name                 getagent().getcontextengineid(), // local engine id                 new octetstring("public"), // default context name                 new octetstring(), // transport tag                 new integer32(storagetype.nonvolatile), // storage type                 new integer32(rowstatus.active) // row status         };     }          public static void main(string[] args) throws ioexception, interruptedexception { agent agent = new agent("127.0.0.1/6666");                 sysuptime=mofactory.createscalar(oid,                              mofactory.createaccess(moaccessimpl.accessible_for_read_only),                               new timeticks(0));                 starttime=system.currenttimemillis();                 agent.registermanagedobject(sysuptime);         agent.start();         while(true) {             system.out.println("agent running...");             thread.sleep(5000);             }     }       public moscalar getsystemid() {      variable var = new integer32((int) (system.currenttimemillis() - starttime));      sysuptime.setvalue(var);     return sysuptime;       }  }

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
