The Busiest-Interval Command
This sec tion d esc rib es the Proc essor Oc c up anc y Busiest-Interval Measurements 
rep ort.
When to Use the Busiest-Interval Command
The main func tion of the busiest-interval
 c ommand  is to p rovid e a long -term 
history rep ort of p otential p erformanc e-related prob lems.
NOTE:
This report p rovid es a c ollec tion of the 20 b usiest 3-minute intervals within 
the last two months. Therefore, this c ommand is most useful to the servic e 
tec hnic ian for investig ating  hab itual performanc e prob lems or those 
problems not reported exactly when they happen.

NOTE:
The field s on this rep ort are the same as on the summary rep ort. However, 
the d ata is c alc ulated  over 3-minute intervals rather than 1-hour intervals.
Using the Busiest-Interval Report
to Resolve Problems
The following  list id entifies some areas that may b e p ursued  when investigating  a 
p rob lem that is b elieved  to b e p roc essor oc c up anc y (load) related .
1. Multiply the numb er in the Total Calls field b y 20 for the id entified  3-minute 
time interval (the time when the p rob lem oc c urred ). If the p roduc t exc eed s 
the ad vertised  BHCC of the switc h, it is the load  for this time interval 
c ausing  the p roblem. If the p rod uc t does not exc eed  the BHCC for the 
switc h, this load  is not the p rob lem.
2. Compare the numb er in the Total Atmp ts field  with the Total Calls field  for 
the id entified  3-minute time interval (the time when the p roblem oc c urred ). 
If the numb er of attemp ts is sig nific antly g reater than the numb er of c alls, 
a sig nific ant p erc ent of the oc c up anc y is d ue to p roc essing  off-hook and  
on-hook stimuli that d o not result in a c omp leted  c all.
3. Examine the hard ware error log  for an exc essive amount of maintenanc e 
activity (for example, a high number of errors).
4. Refer to the list measurements communications-links
 rep ort to 
d etermine if any of the links are rec eiving  an ab normal amount of traffic .
5. Chec k with the users to d etermine if a c ertain feature(s) is used  heavily 
d uring the id entified  time interval.
6. Refer the p rob lem to maintenanc e p ersonnel with the sug g estion they 
c hec k the software error log .

serve a d ifferent func tion than the same link for another switc h. Furthermore, what 
is c onsid ered  to be normal link traffic  for one servic e (for examp le, DCS) may 
vary wid ely from what is c onsidered  to b e normal link traffic  for another servic e 
(for examp le, CMS). Therefore, it is rec ommend ed the c ustomer ob tain a p rinted  
rep ort of what is d eemed  to b e normal traffic  (for eac h switc h) and  use that rep ort 
for c omp arison p urp oses.
This rep ort is of sig nific ant value in d etermining  the long  term imp ac t p roc essor

c ertain typ es of link failure (for examp le, total failure at 1400 hours on link 2 [on

some typ es of intermittent prob lems are not easily rec og nized  with this rep ort.

Data Analysis Guidelines
The following guid elines are intend ed  to show an easy method  for determining  
whether c urrently rep orted  d ata is ac c ep tab le or not. These g uid elines represent 
the minimum you should  d o to verify the rec orded  measurement values are 
c onsistent with exp ec ted  and  historic  values. Perform ad d itional c hec ks as 
nec essary.
To c hec k the ac c eptab ility of hourly d ata, verify the system c loc k was not 
c hang ed  d uring  the measurement hour. If the system c loc k was c hang ed , the 
Minutes field displays double asterisks (for example, 11**
).
During  a p artial system reset (for examp le, 1 or 2 or Cold  1 or Cold  2) the 
measurement d ata is retained  for the affec ted  time interval. However, d uring  a full 
system reset (for examp le, 3, 4, or 5) the measurement d ata is not retained  for the 
affec ted  time interval.
Analyzing the Data
In ord er to c alc ulate the measured  BHCC, use the summary report to c ollec t 
measurement data. Sub sequently, rec ord  d ata for the id entified peak hour on 
Worksheet 5. After rec ord ing  four weeks of d ata, c alc ulate the c olumn averag es 
and  rec ord  the averag es in the ap p rop riate row and  c olumn at the b ottom of 
Worksheet 5.
NOTE:
Before rec ording  eac h d ay’s d ata review the whole day in ord er to ensure 
the p eak hour is not the result of an ab normality (for examp le, c aused  b y a 
snow storm, and  so on). If you d etermine the peak hour is the result of an 
ab normality, d isreg ard  that day’s d ata. Ad d itionally, the weeks you selec t to 
rec ord data from should  NOT b e times of slac k b usiness ac tivity. 
Furthermore, the weeks should NOT b e four c onsec utive weeks; b ut should  
b e the weeks from two or more months of normal b usiness ac tivity.
‘‘WORKSHEET 5’’
 in Appendix A, ‘‘Blank Worksheets’’ p rovid es sp ac e to rec ord  
seven-d ay-p er-week d ata. If your ap p lic ation is a five-d ay op eration, d ata should  
only b e rec ord ed for the five days (Mond ay throug h Frid ay). When averag ing  the 
d ata, take c are to only d ivid e b y the numb er of d ays that d ata was ac tually 
rec ord ed  (for examp le, 20 or 28).
