sequence until the HTTP request is fulfilled. If the HTTP request is
fulfilled, the client sees a successful completion of the request.
Otherwise, the client receives a 503 error from the Director.
http606Redirects is the number of times during the hour that the
Director redirected a request to a server. http606ErrsToClient
is the number of times during the hour that a 503 error is returned to
the client because all redirection attempts failed to fulfill an HTTP
request. A trap threshold,
http606ErrsToClientTh , is available
in the MIB. If http606ErrsToClient reaches
http606ErrsToClientTh during the current hour, a trap is sent.
http606ErrsToClientTh can be set to any positive number. If
http606ErrsToClientTh is set to 0, no trap is sent. Since the
value of http606ErrsToClient during the hour is accumulative
and does not fluctuate, low and high water thresholds are not
necessary for hysteresis.
invalidHttpRequests returns the number of invalid HTTP
requests received by the Director during the hour.
httpServerErrs is the number of timeouts, HTTP errors and
HTTP 606 errors received from servers during the hour.

SSL Monitor Table
A 24-hour history of SSL performance is maintained in
sslMonTable . sslMonTable is indexed by hours of the day, so
sslMonTable is indexed from 0 to 23. To get the current SSL
performance numbers, index the table by the current hour.
currentHour is defined in hp l7-broker-mib.my . Each entry in
the table contains the following information.
sslPeakCpsRate
sslCpsRate
sslConnProcessed
sslTraffic
sslErrs
sslPeakCpsRate is the peak SSL connection/second rate
processed by the SA8220 for the hour. sslCpsRate is the
connection/second rate for the hour.
